v1.0, June 2009

Chapter 1

Getting Acquainted

This chapter provides an overview of the features and capabilities of the ReadyNAS 3200. It also
covers the unit’s physical features, main software, and initial setup steps.

Topics discussed in this chapter include:

• “What is the ReadyNAS 3200?”

• “The Benefits of X-RAID2”

• “Initial Setup and Default Login”

• “The RAIDar Setup Utility”

• “The FrontView Management Console”

What is the ReadyNAS 3200?

NETGEAR ReadyNAS gigabit network storage products provide small and medium sized
businesses with easy-to-use, high-performance network attached storage solutions to share and
protect critical data. Housed in a compact rack mount form factor, the ReadyNAS 3200 supports
up to 12 SATA I or SATA II hard drives via hot-swappable disk trays. Two USB 2.0 ports enable
the connection of USB drives. Based on current drive capacities, the ReadyNAS provides up to
24TB of network attached storage that can easily be expanded as larger capacity drives become
available.

The ReadyNAS enables users across the LAN, WAN, or over the Internet to back up and share
data from Windows, Macintosh, and Linux syst ems. ReadyNAS offers extensible robust high­availability data protection. Its fail-safe features include dual redundant Gigabit Ethernet ports,
support for RAID 0, 1, 5, and 6 plus hot spare, and NETGEAR’s proprietary X-RAID2

TM

for

automatic volume expansion. You can also allocate iSCSI target volumes on a ReadyNAS 3200.
ReadyNAS includes the built-in FrontView Web based graphical user interface and setup wizard

for ease-of-use and setup. ReadyNAS continually monitors the entire system for abnormal
situations or part failures. Status indicators in the hardware and software provide quick system
status readings. It e-mails the network administrator alerts about critical changes in the system.
Also, developers can use the Frontview Add-on SDK to uniquely extend ReadyNAS capabilities.

v1.0, June 2009

The NETGEAR ReadyNAS Community web site is http://readynas.com, where you will find
reviews of new features, tutorials, software updates, documentation, an active user forum and
much more. For a full list of what is new compared with existing ReadyNAS systems, see

ReadyNAS Specifications on ReadyNAS.com.

The Benefits of X-RAID2

X-RAID2 is a proven patent-pending technology that is available only on ReadyNAS. The
ReadyNAS 3200 supports both X-RAID2, the second generation version of X-RAID, and
RAID 0/1/5/6.

A major advantage of X-RAID2 is its ability to automatically expand to include the full space of
new disks. When as little as two of your disks have extra capacity, the data volume will
automatically expand its capacity. The capacity of the data volume increases every time you add a
larger disk, regardless of the capacity of the other disks in the system. X-RAID2 lets you do this
without reformatting your disks and shuffling your data back and forth. The process occurs in the
background, so access to the ReadyNAS 3200 is not interrupted. Furthermore, X-RAID2 supports
multiple parity which provides protection against two simultaneous disk failures. For more on
X-RAID2 and RAID, see Appendix C, “X-RAID2 and RAID”.

Initial Setup and Default Login

Follow the instructions in the NETGEAR Installation Guide that came with your unit to install it.
An electronic copy of the installation guide is on the product CD, on the NETGEAR web site, and
on http://readynas.com. For a list of supported disks, go to http://www.readynas.com/hcl.

Refer to Appendix B, “Share Access from MAC and Linux Systems” for instructions on accessing
shares from Linux and various versions of the MAC OS.

The default IP configuration is set to DHCP; if the unit does not get an IP address, it defaults to

192.168.168.168. The default administrator user name is admin with the default password being

netgear1 (case sensitive).

Note: The RAIDar utility can discover any ReadyNAS on the network without needing

its IP address.

ReadyNAS 3200 Software Manual

The RAIDar Setup Utility

The RAIDar utility enables easy setup and management of all your ReadyNAS units.

It discovers the units in the network, and makes it easy to see the status of the units, and connect to
the FrontView management console you use to manage any ReadyNAS. When you select a
ReadyNAS from the list and click the Setup button, RAIDar opens your default browser, connects
you to the selected ReadyNAS, which prompts you for the user name and password you will use to
log in to FrontView. The default administrator user name is admin with the default password
being netgear1 (case sensitive).

The FrontView Management Console

The FrontView management console operates in two modes: Setup Wizard mode, and Advanced
Control mode. When the unit is in its factory default state, FrontView opens in Setup Wizard
mode.

Use the wizard to perform the initial configuration of the unit. The FrontView Advanced Control
mode provides access to all the available settings. In this mode, you see the menus on the left that
allow you to quickly jump to the screen you want.

The bar at the top provides options to return to the Home screen, refresh the browser window,
display Help where available, or to log out of this session.

Chapter 2

Managing Your ReadyNAS 3200

Setting up and managing the ReadyNAS 3200 Network Attached Storage System in your network
is described in this chapter. This chapter contains the following sections:

• “Customizing Network Settings”

• “Updating the Admin Password”

• “Selecting Services for Share Access”

• “Understanding Volume Management”

• “Adjusting System Settings”

• “Configuration Backup”

Customizing Network Settings

To access network settings, click a the Advanced Control button to display the main menu, then
select Network >. From the Network menu, you can access the configuration pages for network
settings.

Figure 2-1

ReadyNAS 3200 Software Manual

2-2 Managing Your ReadyNAS 3200

v1.0, June 2009

Ethernet Interfaces

Select Network > Interfaces > Ethernet 1 /Ethernet 2 tab pages to specify network interface­specific settings for Standard Settings, Teaming/Failover, VLAN, and Performance Settings.

Standard Setting

In this section, you can specify the IP address, network mask, speed/duplex mode, and MTU
settings. In most networks where a DHCP server is enabled, you can simply specify the Use values

from a DHCP server option to automatically set the IP address and network mask.

• IP Assignment. Select either Use values from a DHCP server or Use values below.

– If you elect to assign the IP address using Use values from a DHCP server, NETGEAR

advises that you set the lease time on the DHCP server/router to a value of at least a day.

Otherwise, you might notice that the IP address of the unit changes even when it has been

powered down for only a few minutes. Most DHCP servers allow you to assign a static IP

address for specified MAC addresses. If you have this option, this would be a good way to

ensure your ReadyNAS 3200 maintains the same IP address even in DHCP mode.

– If you assign a static IP address by selecting Use values below, be aware that the browser

will lose connection to the ReadyNAS 3200 device after the IP address has been changed.

To reconnect after assigning a static IP address, open RAIDar and click Rescan to locate

the device, and then reconnect.

Figure 2-2

Tip: Reserve an IP address for the MAC address of this Ethernet interface in

your DHCP server (or router). This will give you the stability of a fixed IP
address without the effort of maintaining static addresses.

ReadyNAS 3200 Software Manual

Managing Your ReadyNAS 3200 2-3

v1.0, June 2009

• MTU. In some network environments, changing the default MTU value can fix throughput

problems. NETGEAR advises that you leave the default setting otherwise.

Teaming/Failover

In this section, you can select the desired bonding mode. Network teaming provides a way to
aggregate the two network interfaces into a single logical teamed, or bonded, interface. The
teamed interface can provide for enhanced aggregate performance over a logical single interface
while allowing for fail-over support that reduces the number of single points of failure in the
network.

If you plan to use the Teaming/Failover option, connect both interfaces, configure the
T eamin g/Failover options on the Ethernet 1 tab page , then configure the other options for Ethern et
1 and Ethernet 2 accordingly.

The following teaming/fail over options are available.

Figure 2-3

Note: If you plan to reserve an IP address in your DHCP server for the ReadyNAS and

will use the Teaming/Failover option, complete the ReadyNAS bonding of the
Ethernet interfaces before updating the DHCP server address reservation table.

Figure 2-4

ReadyNAS 3200 Software Manual

2-4 Managing Your ReadyNAS 3200

v1.0, June 2009

• Round-Robin: Transmit packets in sequential order from the first available interface to the

next. This mode provides load balancing and fault tolerance.

• Active Backup: Only one interface in the bond is active. A different interface becomes active

if, and only if, the active interface fails. The MAC address of the bonded interface is externally
visible on only one port to avoid confusing the switch.

• XOR: Transmit based on the default simple transmit hash policy (one, or the other but not

both). This mode provides load balancing and fault tolerance.

• Broadcast: Transmit everything on all slave interfaces. This mode provides fault tolerance.

• IEEE 802.3ad LACP: Creates aggregation groups that share the same speed and duplex

settings. Utilizes all interfaces in the active aggregator according to the 802.3ad specification.

• T ransmit Load Balancing: Channel bonding that does not require any special switch support.

The outgoing traffic is distributed according to the current load (computed relative to the
speed) on each interface. Incoming traffic is received by the current interface. If the receiving
interface fails, another interface takes over the MAC address of the failed receiving interface.

• Adaptive Load Balancing: Includes Transmit Load Balancing plus Receive Load Balancing

for IPV4 traffic, and does not require any special switch support. The receive load balancing is
achieved by ARP negotiation.

Note: To get the full performance benefit of an option, provision servers with dual

Ethernet interfaces, and verify that the LAN switch supports the feature that a
ReadyNAS teaming option may require. A mismatch between the LAN switch and
a ReadyNAS teaming option could degrade the throughput of the ReadyNAS.

Note: To use this option, the switch to which the ReadyNAS connects must support

IEEE 802.3ad LACP dynamic link aggregation. If the switch supports this
feature, this is the recommended option.

ReadyNAS 3200 Software Manual

Managing Your ReadyNAS 3200 2-5

v1.0, June 2009

VLAN Settings (Virtual Local Area Network)

In this section, you can specify whether to allow devices residing on different segments of a LAN
to appear in the same segment or, conversely, to allow devices on the same switch to behave as
through they belong to a different LAN.

If you wish to use the ReadyNAS 3200 in a VLAN environment, select the Enable VLAN
support check box, and enter a numeric VLAN ID. You need to reboot the ReadyNAS 3200 for
the VLAN function to take effect.

Performance Settings

In this section, you can the Enable jumbo frames option allows you to optimize the ReadyNAS
3200 for large data transfers.

Figure 2-5

Warning: Do not enable VLAN support unless you are sure that your clients also

support VLAN. Otherwise, you can lose network access to the unit, and you
might need to reinstall the firmware to disable the VLAN setting.

Figure 2-6

Note: Use this option only if your NICs and your gigabit switch support jumbo frames.

The ReadyNAS 3200 supports a 9000 byte frame size. For optimal performance, a
switch capable of this frame size or larger should be used.

ReadyNAS 3200 Software Manual

2-6 Managing Your ReadyNAS 3200

v1.0, June 2009

Global Network Settings

Hostname

The Hostname you specify is used to advertise the ReadyNAS 3200 on your network. Y ou can use
the hostname to address the ReadyNAS 3200 in place of the IP address when accessing the
ReadyNAS 3200 from Windows, or over OS X using SMB. This is also the name that appears in
the RAIDar scan list.

The default hostname is nas- followed by the last three bytes of its primary MAC address.

Default Gateway

The Default Gateway specifies the IP address of the system where your network traffic is routed if
the destination is outside your subnet. In most homes and smaller offices, this is the IP address of
the router connected to the cable modem or your D SL ser vic e.

If you selected the DHCP option in the Ethernet or Wireless tab, the Default Gateway field is
automatically populated with the setting from your DHCP server. If you selected the Static opt ion,
you can manually specify the IP addresses of the default gateway server here.

DNS Settings

The DNS area allows you to specify up to three Domain Name Service servers for hostname
resolution. The DNS service translates host names into IP addresses.

Figure 2-7

ReadyNAS 3200 Software Manual

Managing Your ReadyNAS 3200 2-7

v1.0, June 2009

If you selected the DHCP option in the Ethernet or Wireless tab, the Domain Name Server fields
are automatically populated with the DNS settings from your DHCP server. If you selected the
Static option, you can manually specify the IP addresses of the DNS servers and the domain name
here.

WINS

A WINS (Windows Internet Naming Service) server allows the ReadyNAS 3200 or other devices
on the network to be browsed from other subnets. This can be useful if you wish to browse by
hostname across multiple subnets (for example, over VPN).

You can specify the WINS server IP address, or you make the ReadyNAS your WINS server.

DHCP

DHCP (Dynamic Host Configuration Protocol) service simplifies management of a network by
dynamically assigning IP addresses to new clients on the network. The DHCP tab allows you to
specify this device as a DHCP server.

Figure 2-8

Figure 2-9

ReadyNAS 3200 Software Manual

2-8 Managing Your ReadyNAS 3200

v1.0, June 2009

Select the Enable DHCP service check box if you want the ReadyNAS 3200 device to act as a
DHCP server. This is convenient in networks where DHCP service is not already available.

Route: A Manual Routing Table

The Route tab allows you to specify a manual routing table for each Ethernet interface. You can
use this option to optimize performance. For example, you could configure a manual routing table
to assure that these Ethernet interfaces were directly routed over a fiber backbone to assure that the
unit would not experience the traffic congestion that can build up on a gigabit segment.

Updating the Admin Password

The Security tab allows you to set the administrator password, administer security, and set up the
password recovery feature on the ReadyNAS.

The Admin Password tab allows you to change the administrator user password. The administrator
user is the only user that can access FrontView, and this user has administrative privileges when
accessing shares. Be sure to set a password different from the default password, and make sure that

Note: These options are available only if this device is not already using a DHCP address.

Enabling DHCP service on a network already utilizing another DHCP server will
result in conflicts. If you wish to use this device as a DHCP server, make sure to
specify static addresses in the Ethernet and DNS tabs.

Figure 2-10

Note: The RAIDar utility includes a discovery mechanism that enables it to find any

ReadyNAS on the network without needing to know its IP address. Also, RAIDar
does not require a user name and password to monitor a ReadyNAS.

ReadyNAS 3200 Software Manual

Managing Your ReadyNAS 3200 2-9

this password is kept in a safe place. Anyone who obtains this password can change or erase the
data on the ReadyNAS.

As a safeguard, you are reques ted to ente r a password recovery question, the expected answer , and
an e-mail address. If, in the future, you forget the password, you can go to
https://<ReadyNAS ip_address> /password_recovery. Successfully answering the questions there
resets the Admin Password, which is sent to the e-mail address you enter on this screen.

Figure 2-11

Note: In User or Domain security mode, you can use the admin account to log in to a

Windows share, and perform maintenance on any file or folder in that share. The
admin user also has permission to access all shares to perform backups.

ReadyNAS 3200 Software Manual

2-10 Managing Your ReadyNAS 3200

v1.0, June 2009

Selecting Services for Share Access

Three types of services are available: Standard File Protocols, Discovery Services, and Installed
Add-ins such as streaming services. These different services are explained in the following
sections.

Standard File Protocols

The standard file protocols are common file-sha ring services that allow your workst ation clients to
transfer files to and from the ReadyNAS 3200 using built-in file manager-over -network file
protocols supported by the client operating sys tem.

The available services are:

• CIFS (Common Internet File Service). Sometimes referred to as SMB. This protocol is used

mainly by Microsoft Windows clients, and sometimes by Mac OS X clients. Under Windows,
when you click on My Network Places Network Neighborhood, you are going across CIFS.
This service is enabled by default and cannot be disabled.

• NFS (Network File Service). NFS is used by Linux and Unix clients. Mac OS 9/X users can

access NFS shares as well through console shell access. The ReadyNAS 3200 supports NFS
v3 over UDP and TCP.

Figure 2-12

ReadyNAS 3200 Software Manual

Managing Your ReadyNAS 3200 2-11

v1.0, June 2009

• AFP (Apple File Protocol). Mac OS 9 and OS X works best using this protocol as it handles

an extensive character set. However, in mixed PC and Mac environments, it is advisable to use
CIFS/SMB, unless enhanced character set support is necessary on the Mac.The ReadyNAS
3200 supports AFP 3.1.

• FTP (File Transfer Protocol). Widely used in public file upload and download sites.

ReadyNAS 3200 supports anonymous or user access for FTP clients, regardless of the security
mode selected. If you wish, you can elect to set up port forwarding to nonstandard ports for
better security when accessing files over the Internet.

• HTTP (Hypertext Transfer Protocol). Used by Web browsers. ReadyNAS 3200 supports

HTTP file manager, allowing Web browsers to read and write to shares using the W eb browser.
This service can be disabled in lieu of HTTPS to allow for a more secure transmission of
passwords and data. With the option to redirect default Web access to a specified share, you
can transparently force access to http://readynas_ip to http://readynas_ip/share. This is
useful if you do not want to expose your default share listing page to outsiders. All you need in
the target share is an index file such as index.htm or index.html. You have the option of
enabling or disabling login authentication to this share.

• HTTPS (HTTP with SSL encryption). This service is enabled by default and cannot be

disabled. Access to FrontView is strictly through HTTPS for this reason. If you want remote
Web access to FrontView or your HTTPS shares, you can specify a nonstandard port (default
is 443) that you can forward on your router for better security . You can also regenerate the SSL
key based on the hostname or IP address that users will use to address the ReadyNAS 3200.
This allows you to bypass the default dummy certificate warnings whenever users access the
ReadyNAS 3200 over HTTPS.

• Rsync. An extremely popular and efficient form of incremental backup made popular in the

Linux platform but now available for various other Unix systems as well as Windows and
Mac. Enabling rsync service on the ReadyNAS 3200 allows clients to use rsync to initiate
backups to and from the ReadyNAS 3200.

Discovery Services

Bonjour and UPnP discovery services are included with theReadyNAS 3200. Additional services
that you download and install from www.readynas.com are listed in the Add-ons tab page.

• Bonjour service provides a simple way of discovering various services on the ReadyNAS

3200. Bonjour currently provides an easy way to connect to FrontView, IPP printing, and AFP
services. OS X has built-in Bonjour support, and you can download Bonjour for W indows
from Apple’s website.

• UPnP provides a means for UPnP-enabled clients to discover the ReadyNAS 3200 on your

LAN.

Understanding Volume Management

The ReadyNAS 3200 family offers two RAID volume technologies: Flex-RAID, utilizing the
industry-standard RAID levels 0, 1, 5 and 6; and X-RAID2, the NETGEAR-patented expandable
RAID technology.

Your system comes preconfigured with X-RAID2. However, you can switch between the two
modes through a factory default reset process described in the ReadyNAS 3200 Hardware
Manual.” For more on X-RAID2 and RAID, see Appendix C, “X-RAID2 and RAID”.

Advantages of X-RAID2 and Flex-RAID

There are advantages to both technologies.

•Flex-RAID:

– The default volume can be deleted and re-created, with or without snapshot reserved

– Hot spare disk is supported.
– Full volume management is available. You can create RAID level 0, 1, 5 or 6 volumes,

specify the volume size, delete a disk from a volume, assign a hot spare, and so on.
– Multiple volumes are supported, each with a different RAID level, snapshot schedule and

disk quota definition.

– Each disk can be replaced, one by one, then rebuilt; after the last disk is replaced, another

data volume using the newly added capacity can be configured.

• X-RAID2:

– One-volume technology, but supports volume expansion, either with the addition of more

disks or the replacement of an existing disk with larger capacity disks.
– You can start out with one disk, and add more disks as you need them or can afford them.
– Volume management is automatic. Add a second disk, and it becomes a mirror to the first.

Add a third disk and your capacity doubles; add a fourth, and your capacity triples—the

expansion occurring while redundancy is maintained.
– In the future, you will be able to replace disks, one at a time, have each one finish

rebuilding and, after new redundant space becomes available, your volume will

automatically expand to utilize the new capacity.

Volume Management for Flex-RAID

If you want to reconfigure the default Flex-RAID volume C, split it into multiple volumes, specify
a different RAID level, or specify a larger reserved space for snapshots, you need to reconfigure
your volume. The first step is to delete the existing volume you want to replace.

Deleting a Volume

To delete a volume, select the Volume tab of the volume you wish to delete (if there are multiple
volumes) and click Delete Volume (in this case only Volume C is configured).

Warning: Make sure that you back up the files you wish to keep before deleting a

volume. All shares, files, and snapshots residing on that volume will be

deleted and are non-recoverable!

Figure 2-15

ReadyNAS 3200 Software Manual

Managing Your ReadyNAS 3200 2-15

v1.0, June 2009

You are asked to confirm your intention by typing DELETE VOLUME.

Adding a Volume

After deleting the volume, the Add Volume tab lists the available configurable space on the hard
disks. All the disks are selected by default. You can specify a hot spare disk if you wish. A hot
spare remains in standby mode and automatically regenerates the data from a failed disk from the
volume. A hot spare disk is available for RAID level 1 and RAID level 5 only if there are enough
disks to fulfill the required minimum plus one.

.

To add a volume:

1. Select the hard disks. In this example, we select the first three disks and elect not to specify

any of them as a hot spare.

2. Select the RAID level. RAID level determines how the redundancy, capacity utilization, and

performance are implemented for the volume. Typically in a configuration of three or more
disks, RAID level 5 is recommended.

In our example, we selected RAID level 5 for the three selected disks.

Figure 2-16

Figure 2-17

v1.0, June 2009

3. Specify the reserve space for a snapshot. Next, select the percentage of the volume you wish to

allocate for snapshots. You can specify 0 if you wish to disable snapshot capability, or you can
specify a percentage in 5 percent increments from 5 to 50 percent.

The percentage represents the amount of data you think changes while the snapshot is active.
This typically depends on how often you schedule your snapshot to occur (see “MAC OS X

Time Machine Backup” on page 4-9), and the maximum amount of data (plus padding) you

think changes during that time. Make sure to allocate enough space for a worst case as the
snapshot becomes unusable when its reserved space runs out.

In our example, we selected 10 percent of the volume to be reserved for snapshots.

4. Specify the desired volume size. After you specify the volume parameters, enter the

appropriate volume size—if you wish to configure a smaller volume size than the maximum
displayed. The resulting volume will be approximately the size that is specified.

5. Click Apply, and wait for the instruction to reboot the system. It typically takes about 1 minute

before you are notified to reboot.
After rebooting, you are notified by e-mail when the volume has been added. Use RAIDar to

reconnect to the NAS device.

RAID Settings

After you have added a volume, you can return to the Volume tab and click the RAID Settings tab
to display the current RAID information and configuration options for the volume.

Note: If you do not reserve any space for snapshots, the snapshot tab is not displayed

in the Volume tab.

Notice that the disk on Channel 4 that we did not configure is listed in the Available Disks section.
We can add this disk as a hot spare by clicking Make hot spare.

We can also remove a disk from the volume by clicking Remove. The volume will still be
available but in a non-redundant state. An additional disk failure would render this volume
unusable.

The Locate option is a way to verify that a disk is correctly situated in the expected disk slot.
Clicking Locate causes disk LED to blink for 15 seconds.

Volume Management for X-RAID2

Most people want to either add redundancy or expand their data volume. X-RAID2 enables this
without the headaches usually associated with doing so.

Adding a Second Disk for Redundancy

A one-disk X-RAID2 device has no redundancy and provides no protection from a disk failure.
However, if and when you feel the need for redundancy, simply add a new disk with at least the
capacity of the first disk. Depending on the size of the disk, within a few hours, your data volume
will be fully redundant. The process occurs in the background, so access to the ReadyNAS 3200 is
not interrupted.

Figure 2-18

Note: The Remove operation is a maintenance feature. Do not use it in a live

environment. Its function is equivalent to hot-removing the disk or simulating a
disk failure.

ReadyNAS 3200 Software Manual

2-18 Managing Your ReadyNAS 3200

v1.0, June 2009

Adding More Disks

At a certain point, you will want more capacity. With typical RAID volumes, you have to back up
your data to another system (with enough space), add a new disk, reformat your RAID volume,
and restore your data back to the new RAID volume.

With X-RAID2, you simply add the third disk using the ReadyNAS hot-swap disk tray. If you are
adding multiple disks at the same time, power down the ReadyNAS, add the disk(s), and power
back on. The X-RAID2 device initializes and scans the newly added disk(s) for bad sectors in the
background. You can continue working normally without any lag in performance.

Reboot the ReadyNAS to initiate the background expansion. You can continue using the
ReadyNAS while the expansion proceeds. You will get an email notice when the expansion
completes.

After you receive your e-mail, the ReadyNAS 3200 will have been expanded with the capacity
from your new disk(s).

Replacing Disks for More Capacity

When you need more disk space and larger disks are available at an attractive price, you can
expand your volume capacity by replacing the existing disks.

The ReadyNAS 3200 supports hot-swapping, so you can swap disks withou t powering do wn. The
Replace the first disk, and the ReadyNAS will detect that a new disk was put in place and
resynchronizes the disk with data from the removed disk. This process can take 30 minutes or
longer, depending on disk capacity, but you can use the ReadyNAS while the new disk
synchronizes. Upon completion, replace the second disk with another large-capacity disk, allow
that disk to synchronize. X-RAID2 lets you expand the volume when a minimum of two disks are
replaced. At one time, you cannot replace disks that add up to more than the current volume
capacity. When you have replaced the desired number of disks, simply reboot the ReadyNAS to
initiate the background expansion. You can continue using the ReadyNAS while the expansion
proceeds. You will get an email notice when the expansion completes.

Changing between X-RAID2 and Flex-RAID Modes

You can switch between X-RAID2 and Flex-X-RAID modes. The process involves setting the
ReadyNAS 3200 to the factory default and using RAIDar to configure the volume during a 10­minute delay window during boot. Setting the ReadyNAS 3200 to the factory default setting will
erase all its data. See the ReadyNAS 3200 Hardware Manual for more information.

iSCSI Target Volumes

The iSCSI target service enables you to create one or more iSCSI target volumes on the
ReadyNAS.

The iSCSI (Internet SCSI) protocol allows clients called initiators to send SCSI commands to
SCSI storage devices called targets on remote servers. It is a popular Storage Area Network (SAN)
protocol, allowing organizations to consolidate storage into da ta center storage arrays while
providing hosts such as databases and web servers with the illusion of locally-attached disks.
Unlike Fibre Channel, which requires special-purpose cabling, iSCSI can be run over long
distances using existing network infrastructure.

An iSCSI initiator sends SCSI commands over an IP network to an iSCSI target. Software to
provide an iSCSI initiator is available for most mainstream operating systems. Unlike network file
services where you access files in network share folders, the iSCSI target presents itself as a virtual
block device and can be treated like a locally attach ed disk to the client system acting as the iSCSI
initiator . Windows for instance could run FA T32 or NTFS on the iSCSI tar get device, and treat the
device as though it was locally attached.

To configure an iSCSI target volume on the ReadyNAS, go to Volumes > Volume Settings >
iSCSI.

To enable iSCSI support, click Create iSCSI Target, and enter the desired name of the target and
the capacity you wish to reserve for this target device. Maximum capacity is slightly less than the
full free space on the ReadyNAS. If you wish to enable authentication for access, enable CHAP
authentication and specify the user name and password. The password needs to be at least 12
characters long.

Go to http://readynas.com/iSCSI on ReadyNAS.com for instructions on setting up iSCSI access
from various operating systems.

USB Volumes

The USB tab displays the USB disk and flash devices connected to the ReadyNAS 3200, and
offers various options for these devices. A flash device appears as USB_FLASH_1 and a disk
device appears as USB_HDD_1. If you have multiple devices, they appear appended by an
increasing device number; for example, USB_HDD_2. If the device contains multiple partitions,
the partitions are listed beneath the main device entry.

Partitions on the storage devices must be one of the following file system formats: FAT32, NTFS,
Ext2, or Ext3.

Figure 2-20

ReadyNAS 3200 Software Manual

Managing Your ReadyNAS 3200 2-21

v1.0, June 2009

To the right of the access icons are command options. The following commands are available:

When the USB device is unmounted, you have the option of renaming it. The next time the same
device is connected, it will use the new name rather than the default USB_FLASH_n or
USB_HDD_n naming scheme.

The USB storage shares are listed in the Share screen, and access restrictions can be specified
there. The share names reflect the USB device names. USB storage devices are shared using the
name of the device appended with the partition number. You can change the base device name in
Volumes > USB Storage, if you want.

USB Flash Device Option

Toward the lower portion of the USB Storage screen is the USB Flash Device Option section (see

Figure 2-20 on page 2-20). There, you can elect to copy the content of a USB flash device

automatically on connection to a specified share. Files are copied into a unique timestamp folder to
prevent overwriting previous contents. This is useful for uploading pictures from digital cameras
and music from MP3 players without needing to power on a PC.

In User security mode, an additional option to set the ownership of the copied files is available.

Disconnect This option prepares the USB partition for disconnection by correctly unmounting the file

system. In most cases, you can safely disconnect the device without first unmounting;
however, the Disconnect command ensures that any data still in the write cache is
written out to the disks and that the file system is properly closed. The Disconnect option
unmounts all partitions on the device. Once disconnected, physically remove and re­connect to the ReadyNAS to regain access the USB device,.

Locate In cases where you attach multiple storage devices and wish to determine which device

corresponds to the device listing, the Locate command causes the device LED to blink, if
present.

Format FAT32 This option formats the device as a FAT32 file system. FAT32 format is easily

recognizable by most newer Windows, Linux, and Unix operating systems.

Format EXT3 This option formats the device as an EXT3 file system. Select this option if you will be

accessing the USB device mainly from Linux systems or ReadyNAS devices. The
advantage of EXT3 over FAT32 is that file ownership and mode information can be
retained using this format, whereas this capability is not there with FAT32. Although not
natively present in the base operating system, Ext3 support for Windows and OS X can
be added.

Alerts, Alert Contacts, Alert Settings, SNMP, and SMTP

In the event of a device or an enclosure failure, a quota violation, low-disk space warning, and
other system events requiring your attention, e-mail alerts are sent.

The Alerts screen is accessed by selecting System > Alerts from the main menu.

Contacts

The Contacts tab allows you to specify up to three e-mail addresses where system alerts will be
sent. The ReadyNAS 3200 device has a robust system monitoring feature and sends e-mail alerts if
something appears to be wrong or when a device has failed. Make sure to enter a primary e-mail
address and a backup one if possible.

Figure 2-23

Some e-mail addresses can be tied to a mobile phone. This is a great way to monitor the device
when you are away from your desk.

Settings

This ReadyNAS 3200 device has been preconfigured with mandatory and optional alerts for
various system device warnings and failures. The Settings tab allows you to control the settings for
the optional alerts.

You should keep all alerts enabled; however, you might choose to disable an alert if you are aware
of a problem and wish to temporarily disable it.

At the bottom of the screen in the Other Alert Settings section, there are a couple of additional
options of note. Selecting the Power-off NAS when a disk fails or no longer responds option
gracefully powers off the ReadyNAS 3200 if a disk failure or a disk remove event is detected.
Selecting the Power-off NAS wh en dis k temperature exceeds safe level gracefully powers off
the ReadyNAS 3200 when the disk temperature exceeds the nominal ran ge .

SNMP

If you utilize an SNMP management system such as HP OpenView or CA UniCenter to monitor
devices on your network, you can set up the ReadyNAS 3200 device to work with this
infrastructure.

To set up SNMP service:

1. Select the SNMP tab to display the SNMP settings.

2. Select the Enable SNMP service check box. You can leave the Community field set to
public, or specify a private name if you have opted for a more segregated monitoring scheme.

3. Enter a host name or an IP address in the Trap destination field. This is where all trap

messages will be sent. The following system events generate a trap:

• Abnormal power voltage

• Abnormal board enclosure temperature

•Fan failure

• UPS connected

• UPS detected power failure

• RAID disk sync started and finished

• RAID disk added, removed, and failure

• Snapshot invalidated

4. If you wish to limit SNMP access to only a secure list of hosts, specify the hosts in the Hosts
allowed access field.

5. Click Apply to save your settings.

When you have saved the SNMP settings on the ReadyNAS 3200, you can import the NETGEAR

SMTP

The ReadyNAS 3200 device has a built-in e-mail message transfer agent (MTA) that is set up to
send alert e-mail messages from the device. Some corporate environments, however, might have a
firewall that blocks untrusted MTAs from sending out messages.

If you were unable to receive the test message from the Alerts Settings tab, it might have been
blocked by the firewall. In that case, specify an appropriate SMTP server in this tab.

If your firewall setting prevents alert messages from being sent by the embedded SMTP server, or
if your ISP blocks SMTP port 25, enter a remote SMTP server that alert email messages can be
routed through. Some SMTP servers will reject non-fully qualified histamines, so you may need to
change the hostname of this device to FQDN format in the Network tab (see “Hostname” on

page 2-6), i.e. use myhost.domain.com instead of myhost.

Internet Service Providers (ISPs) for home might also block untrusted MTAs. Furthermore, they
might allow you to specify their SMTP server but requires that you enter a user login and password
to send out e-mail—this is common with most DSL services. If this is the case, simply enter the
user name and password in the fields provided.

The TLS option allows the SMTP server and client to use transport-layer security to provide
private, authenticated communication over the Internet. This gives SMTP agents the ability to
protect some or all of their communications from eavesdroppers and attackers, and may be
required by the SMTP server you are using.

Updating ReadyNAS 3200 Firmware

The ReadyNAS 3200 device offers the option of upgrading the operating firmware either
automatically using the Remote Update option or by manually loading an update image
downloaded from the NETGEAR website.

Updating from the NETGEAR Web Site

If the ReadyNAS 3200 has Internet access the easiest update option is the Remote option. The
update process updates only the firmware image and does not modify your data volume. However,
it is always a good practice to back up your data before you perform an upd ate.

T o use the Remote option, select Update from the main menu and then click the Remote tab. Click

Check for Updates to check for updates on the NETGEAR update server.

The ReadyNAS 3200 offers User and Domain security access options.

Figure 3-1

ReadyNAS 3200 Software Manual

3-2 Managing User Access

v1.0, June 2009

Select the most appropriate option based on the required level of security and your current network
authentication scheme.

• User. User security mode is the recommended selection for the small and medium-size office
or workgroup environments. This mode allows you to set up share access restrictions based on
user and group accounts. Access to shares requires proper login authentication, and you can
specify which users and/or groups you wish to offer access. As an example, you might want to
restrict company financial data to just users belonging to one particular group. In this security
mode, the administrator need to set up and maintain user and group accounts on the
ReadyNAS device itself.

• Domain. The Domain security mode is most appropriate for larger department or corporate
environments, where a centralized Windows-based domain controller or active directory
server is present. The ReadyNAS device integrates in this environment by creating a trusted
relationship with the domain/ADS authentication server and allowing all user authentications
to occur there, eliminating the need for separate account administration on the device itself.

User Security Mode

This option is ideal for small and medium-size offices or workgroups. Select this option if you
would like to control access to shares based on user or group accounts and if your network does
not utilize a domain controller for authentication.

If you select this option, you will need to create a user account for anyone accessing this device.
This option supports setting disk quotas on a per-user or per-group basis.

In User security mode, you specify a workgroup name, and create user and group accounts. You
have control over how much disk space is allocated for each user or group.

Each user is given a home share on the ReadyNAS 3200 device that the user can use to keep
private data such as backups of the user’s PC. This home share is accessible only by that user and
the administrator in order to perform backups of the private shares. The option to automatically

Figure 3-2

ReadyNAS 3200 Software Manual

Managing User Access 3-3

v1.0, June 2009

generate the private home share is controlled in the Accounts/Preferences tab, and you can disable
it if you wish.

To set up the ReadyNAS 3200 for this security mode, you need the following information:

• Workgroup name

• Group names you wish to create (for example, Marketing, Sales, Engineering)

• User names you wish to create (plus e-mail addresses if you will be setting disk quotas)

• Amount of disk space you want to allocate to users and groups (optional)

To change or set a workgroup name:

1. Select the User radio button.

2. Enter the name you want to use in the Workgroup field in the User section. The name can be

the workgroup name that is already used on your Windows network.

3. Click Apply to save your changes.

Note: Private user shares are accessible only by users using CIFS (Windows) or AFP

(Mac), and FTP/S protocols.

Domain Security Mode

If you choose the Domain security mode option, you need to create a trusted relationship with the
domain controller or the active directory server (ADS) that will act as the authentication server for
the ReadyNAS 3200 device.

You need the following information:

• Domain name.

• Domain administrator login.

• Domain administrator password.

• If using ADS, you will need:
– DNS name of the ADS realm
– OU (Organization Unit). You can specify nested OUs by separating OU entries wi th

commas. The lowest level OU must be specified first.

You can elect to have the ReadyNAS 3200 automatically auto-detect the domain controller, or you
can specify the IP address. Sometimes auto-detect fails, and you need to supply the IP address of
the domain controller to join the domain.

If you have a large number of users in your domain, you may want to clear the Display users from
trusted domains... check box. The FrontView management system might slow down to an
unusable state.

Click Apply to join the domain. If Auto-detection is successful, users and groups from the domain
now have login access to the shares on this device.

Accounts are managed on the domain controller. The ReadyNAS 3200 simply pulls the account
information from the controller and displays it in the Accounts tab screen if you have the Display
users from trusted domains… option enabled. If you wish, you can assign a disk quota to the
domain users and groups. If e-mail addresses are specified, users are automatically notified when
approaching and reaching their quotas.

Setting Up User and Group Accounts

In the User & Group Accounts security mode, the Accounts tab screen allows you to manage
user and group accounts on the ReadyNAS 3200.

Note: At this time you can use of the ReadyNAS 3200 in a domain environment that

serves up to 32,000 users.

Managing Groups

To add a new group:

1. Select Manage Groups from the drop-down menu in the upper right corner.

2. Select the Add Group tab if it is not already selected. You can add up to five groups at a time.

If you expect to have just one big set of users for one group, you can forego adding a new
group and accept the default users group.

3. Click Apply to save your settings.

If you want, a user can belong to multiple groups. Once you have created user accounts, you can
specify secondary groups that the user can belong to. This allows for finer-grain settings for share
access. For instance, you can have user Joe in the Marketing group also belong to the Sales group
so Joe can access shares restricted to only the Marketing and Sales groups.

While adding a new group, you can specify the amount of disk space you wish to allocate that
group by setting a disk quota. A value of 0 denotes no limit. You can also set the Group ID, or
GID, of the group that you are adding. You can leave this field blank and let the system
automatically assign this value unless you wish to match your GID to your NFS clients.

Setting Accounts Preferences

You can set various account defaults by selecting Preferences option from the pull-down menu.

Changing User Passwords

There are two ways in which user passwords can be changed in the User security mode. The first
way is for the administrator to change the passwords by selecting Security > User & Group
Accounts and then selecting Manage Users from the pull-down menu. The other and preferred
way is to allow users to change their own passwords. This relieves the administrator from this task
and encourages users to change their passwords on a more regular basis for enhanced security.

Users can use the Web browser and their existing password to log in to https://<ip_addr>/ to
access the Web share listing page. Then select the Password tab, and follow the prompts to set a
new password.

In Share and Domain security mode, the Password tab does not appear.

Managing Shares

Shares enable you to organize the information stored on a volume, and administer who has access
to that information. For example, generic policies and forms like blank expense reports everyone
should be able to access, compared with sensitive data like financial information only the finance
group should be able to access.

The Shares menu provides all the options pertaining to share services for the ReadyNAS 3200
device. This entails share management (including data and print shares), volume management, and
share service management.

Adding Shares

To add a share:

1. From the main menu, select Volumes > Volume Settings. If more than one volume is

configured, click on the volume you wish to add the share.

Note: User passwords in Domain mode must be set on the domain or ADS server.

The columns to the left of the Delete check box represent the services that are currently available.
The access icons in those columns summarize the status of the service and the access rights to the
share for each of the services. Move the mouse pointer over the access icons to view the access
settings.

The settings are as follows:

• Disabled. Access to this share is disabled.

• Read-only Access. Access to this share is read-only.

• Read/Write Access. Access to this share is read/write.

• Read Access with exceptions. Either (1) access to this share is read-only and allowed only for

specified hosts, (2) access is read-only except for one or more users or groups that are granted
read/write permission, or (3) access is disabled except for one or more users or groups that are
granted read-only privilege.

• Write Access with exceptions – Either (1) access to this share is read/write and allowed only

for specified hosts, (2) access is read/write except for one or more users or groups that are
restricted to read-only access, or (3) access is disabled except for one or more users or groups
that are granted read/write privilege.

You can click on the access icons to display the Share Options screen, where you can set the access

Share Access Restriction. If you wish to limit share access to particular users and/or groups,
you can enter their names in the Read-only users, Read-only groups, Write-enabled users, and
Write-enabled group fields. The names must be valid accounts, either on the network storage or
on the domain controller. Note that access control differs slightly from service to service.

For instance, if you wish to allow read-only access to all and read/write access only user fred and
group engr, you would set the following:

• Default: Read-only

• Write-enabled users: fred

• Write-enabled groups: engr
If you wish to limit this access only to hosts 192.168.2.101 and 192.168.2.102, set the following:

• Default: Read-only

• Hosts allowed access: 192.168.2.101, 192.168.2.102

• Write-enabled users: fred

• Write-enabled groups: engr
If you wish to specify some users and groups for read-only access and some for read/write access,

and disallow all other users and groups, enter the following:

• Default: Disabled

• Hosts allowed access: 192.168.2.101, 192.168.2.102

• Read-only users: mary, joe

• Read-only groups: marketing, finance

• Write-enabled users: fred

• Write-enabled groups: engr
If you wish to grant guests access to this share, check the Allow guest access checkbox.

Share Display Option. Restricting access to a share does not prevent users from seeing the
share in the browse list. In certain instances, you might not want this, such as for backup shares
that you might want to prevent users from seeing.

To hide a share, select the Hide this share… check box. Users who have access to this share must
specify the path explicitly. For example, to access a hidden share, enter \\host\share in the
Windows Explorer address bar.

Recycle Bin. The ReadyNAS 3200 can have a Recycle Bin for each share for Windows users.
The Enable Recycle Bin option is shown at the bottom of the CIFS screen.

When this check box is selected, whenever you delete a file, the file gets inserted into the Recycle
Bin folder in the share rather than being permanently deleted. This allows for a grace period during
which users can restore deleted files.

You can specify how long to keep the files in the Recycle Bin and how large the Recycle Bin can
get before files get permanently erased.

Advanced CIFS Permission. The Advanced CIFS Permission section offers options for
setting the default permission of new files and folders created through CIFS. The default
permission of newly created files is read/write for the owner and owner’s group and read-only for

Figure 3-13

others (that is, everyone). Permission for newly created folders is read/write for everyone. If the
default does not satisfy your security requirement, you can change it here.

Opportunistic locking (often referred to as oplocks) enhances CIFS performance by allowing files
residing on the NAS to be cached locally on the Windows client, thus eliminating network latency
when the files are constantly accessed.

Advanced Options

The Advanced Options tab offers advanced low-level file manipulation options that can affect file
access through all file protocol interfaces. Care should be taken before you use these options as
anything that changes ownership and permissions might not be easily reversible.

Advanced Share Permission. The Advanced Share Permission section offers the options to
override the default ownership and permission of the share folder on the embedded file system and
to permeate these settings to all files and folders residing on the selected share. The Set ownership
and permission for existing files and folders option performs a one-time change. Depending on
the size of the share, this can take a while to finish.

You can also grant rename and delete privilege to non-owners of the files option. In a collaborative
environment, you might want to enable this option. In a more security-conscious environment,
disable this option.

One useful application for a Web share is to set up an internal company website. You can copy
HTML files to the Web share using Windows, Mac, NFS, or HTTP. When you set HTTP access to
read-only, html files, including index.htm and index.html, can be viewed using any web browser.

Share Access via FTP/FTPS

To access the share via FTP in Share security mode, log in as “anonymous” and use your e-mail
address for the password.

To access the share, use the appropriate user login and password used to access the ReadyNAS.
For better security , use an FTPS (FTP-SSL) cl ient to connect to the ReadyNAS FTP service. With
FTPS, both the password and data are encrypted.

Note: Files created under the Web file manager can be deleted only under this file

manager when accessed via HTTP/S through a browser. The only exception is for
the admin user. The admin user can change or delete any files created over the web
via any protocol. Files not created from this file manager can be modified within
the file manager but cannot be deleted here.

Remote Access

You can remotely access your Re adyNAS 3200 from the Internet via the ReadyNAS remote
feature, or via the FTP and HTTP protocols. This section provides instruct ions for enabling remote
access to your ReadyNAS 3200.

ReadyNAS Remote

ReadyNAS Remote is a web based service that enables drag & drop file transfers from the
Windows File Explorer or the Mac Finder over CIFS/SMB. All file permissions and share security
settings are retained as if you were on the LAN. All data are transmitted securely over an
encrypted tunnel. The setup and use of ReadyNAS Remote is intuitively easy.

Follow these steps to enable ReadyNAS Remote:

1. Install the ReadyNAS Remote client software for Mac or PC. The PC screens are shown below

but the Mac steps are nearly identical.

a. Log in to FrontView and go to > Services > ReadyNAS Remote.
b. Click the “here” link (http://www.readynas.com/?p=1435) to download the client software

from ReadyNAS.com and view the setup tutorial.

c. Install the ReadyNAS Remote client software.

Figure 3-21

Note: Desktop firewall software can block the ReadyNAS Remote client. If the

PC or Mac is running firewall software like Norton, Zone Alarm, or
Kaspersky, you will need to configure your desktop firewall to give
permission to the ReadyNAS Remote client software.

• Authentication mode: There are two authentication modes:

• Anonymous: No login information required for FTP users.

• User: Users will need an account configured on the ReadyNAS from either user or

domain security mode.

• Allow upload resumes: This option allows users to finish uploading a file to the FTP

share if the connection had been previously interrupted. Without this option enabled, if the
connection is dropped at 50% completion, the file upload must restart from the beginning.

• Passive ports: This port range is required to enable remote access to the ReadyNAS from

over the Internet. This port range should be adjusted to the maximum number of
concurrent sessions the user expects to run at one time. If you expect frequent concurrent
access from many users, double this number, as each FTP user will consume a passive
port.

• Masquerade as: This field is for adjusting the hostname that the FTP server reports to an

FTP client.

2. Configure the FTP share access options.

Change the Share Access Restrictions to allow FTP access to the share according to the user
permissions you require.

– SSL key host: This field lets you configure the hostname used for the ReadyNAS to

generate its SSL certificate, and then create a new SSL certificate. It is advised users
update this field to match the current IP address of the ReadyNAS and then generate a
new SSL certificate to avoid future certificate errors from their web browser.

2. Configure the HTTP/S share access options.

Change the Share Access Restrictions to allow HTTP access to the share according to the user
permissions you require.

3. Enable W e bDAV support: W e bDAV is an HTTP connection method that can allow drag and

drop file transfers similar to what users may experience with their standard Windows or Mac
OSX computer. See ReadyNAS.com for a how-to explanation of how to set up WebDAV:

http://www.readynas.com/?p=126

Note: In this scenario, it is best to have a fixed IP configuration for the

ReadyNAS so that the certificate will remain valid. Also, if the WAN IP
address configuration is DHCP, then it is advisable to use a Dynamic DNS
service to access the ReadyNAS via a persistent fully qualified domain
name a DDNS service provides rather than via an IP address.

Enabling Rsync and Specifying Rsync Rights

Enable rsync at the bottom of the Services > Standard File Protocols page to display the rsync icon
next to each share. Click the rsync icon to view the rsync configuration options. Select the Default
Access rights, and assign a user name and password. You will need to specify this when doing an
rsync backup. Unlike other protocols, rsync uses arbitrary user name and password that is specific
only for rsync access. Run rsync over SSH to encrypt rsync data transfers. Access to the share
through rsync is identical regardless of the security mode. The user account you specify does not
need to exist on the ReadyNAS or a domain controller.

Here is an example of a way for a Linux client to list the content of a ReadyNAS rsync share with
no user name and password defined:

# rsync <ipaddr>::backup

To recursively copy the content of a share to /tmp:

# rsync -a <ipaddr>::backup /tmp

To do the same except with a login user and password hello, enter:

# rsync -a user@<ipaddr>::backup /tmp
Password: *****

Securing Your Data

This chapter explains how to back up the data from your ReadyNAS.

• “Configuring Backup Jobs”

• “MAC OS X Time Machine Backup”

• “Backing Up the ReadyNAS to a USB Dri ve ”

• “Backing Up to the Web with the ReadyNAS Vault Service”

Configuring Backup Jobs

The Backup Manager integrated with the ReadyNAS 3200 allows the ReadyNAS 3200 to act as a
powerful backup appliance. Backup tasks can be controlled directly from the ReadyNAS 3200
without the need for a client-based backup application.

With the flexibility to support incremental backups over CIFS/SMB, NFS, and rsync protocols,
and full backups over FTP and HTTP protocols, the ReadyNAS 3200 can act as a simple central
repository for both home and office environments. And with multiple ReadyNAS 3200 systems,
you can set up one ReadyNAS 3200 to back up another directly.

Adding a New Backup Job

The backup source can be located remotely , it can be a public or a private home share, it can be an
iSCSI individually addressable (logical) SCSI device (a logical unit number or LUN), or it can be
all home shares on the ReadyNAS 3200.

ReadyNAS 3200 Software Manual

4-2 Securing Your Data

v1.0, June 2009

To create a new backup job, select Add a New Backup Job and follow the 4-step procedure.

Step 1 – Select Backup Source

A USB device appears as a share, so if you want to back up a USB device, select a share name. If
you want to back up data from a remote source, sele ct from one of the following:

• iSCSI. If iSCSI has been enabled, you can select this if you wish to back up an iSCSI LUN.

• Remote Windows/NAS (Timestamp). Select this if you wish to back up a share from a

Windows PC. Incremental backups use timestamps to determine whether files should be
backed up.

• Remote Windows/NAS (Archive Bit). Select this if you wish to back up a share from a

Windows PC. Incremental backups use the archive bit of files, similar to Windows, to
determine whether they should be backed up.

• Remote Website. Select this if you wish to back up a website or a website directory. The

backed up files include files in the default index file and all associated files, as well as all
index file links to web page image files.

• Remote FTP site. Select this if you wish to back up an FTP site or a path from that site.

• Remote NFS server. Select this option if you wish to back up from a Linux or UNIX server

across NFS. Mac OS X users can also use this option by setting up a NFS share from the
console terminal.

Figure 4-1

ReadyNAS 3200 Software Manual

Securing Your Data 4-3

v1.0, June 2009

• Remote Rsync server. Select this if you wish to perform backups from a rsync server. Rsync

was originally available for Linux and other flavors of UNIX, but has lately become popular
under Windows and Mac for its efficient use of incremental file transfers. This is the preferred
backup method between two ReadyNAS devices. For instructions on enabling rsync, see

“Enabling Rsync and Specifying Rsync Rights” on page 3-26.

• Share. Select this if you wish to back up a ReadyNAS share.

• Volume. Select this if you wish to back up an entire volume which includes all shares on it.

• USB Device. Select this if you wish to back up a USB connected drive. Choose where the

device is connected.
— Rear Top Port
— Rear Bottom Port

• All Home Shares. Select this if you wish to back up all private home shares on the

ReadyNAS.

Observe Correct Backup Source and Destination Path Syntax. Once you have selected
a backup source, you can enter the path from that source. If you selected a ReadyNAS 3200 share,
you can either leave the path blank to backup the entire share, or enter a folder path. If you selected
a remote source, each remote protocol uses a slightly different notation for the path.

Figure 4-2

Note: Depending on the operating system you are working with, observe the correct

backslash (forwarded or backward) accordingly.

• Examples of an NFS path:

myserver:/mypath

192.168.0.101:/mypath/myfolder

• Examples of a Rsync path:

myserver::mymodule/mypath

192.168.0.101::mymodule/mypath

• Examples of a Rsync path over an ssh link:

192.168.0.101:/mymodule/mypath

• Examples of a local path:

myfolder
media/Videos
My Folder
My Documents/My Pictures

With a remote source, you might need to enter a login and password to access the share. If you are
accessing a password-protected share on a remote ReadyNAS 3200 server configured for Share
security mode, enter the name of the share name for login.

To make sure that you have proper access to the backup source, click Test Connection before
continuing.

Securing Your Data 4-5

v1.0, June 2009

Step 2 – Select Backup Destination

The Step 2 process is almost identical to Step 1 except that you are now specifying the backup
destination. If you selected a remote backup source, you need to select a public or a private home
share on the ReadyNAS 3200 (either the source or destination must be local to the ReadyNAS

3200). If you selected a ReadyNAS 3200 share for the source, you can either enter another local
ReadyNAS 3200 share for the destination, or you can specify a remote backup destination.

The remote backup destination can be any of the items on the list, including an iSCSI LUN (if
iSCSI is enabled), a Remote Windows PC/ReadyNAS 3200 system, Remote Website, a R emote
FTP site, a Remote NFS Server, a Remote Rsync server, a ReadyNAS Share, or a USB Device
(Front, Back Top or Bottom). Note that you can select rsync for a remote ReadyNAS 3200 if it is
configured to serve data over rsync.

Step 3 – Choose Backup Schedule

You can select a backup schedule as frequently as once every 4 hours daily or just once a week.
The backup schedule is offset by 5 minutes from the hour to allow you to schedule snapshots on
the hour (snapshots are almost instantaneou s) and perform backups of those snapshots (see “MAC

OS X Time Machine Backup” on page 4-9 to set up a snapshot schedule).

If you wish, you can elect not to schedule the backup job so that you can invoke it manually
instead by clearing (deselecting) the Perform backup every... check box. (You might want to do
this if your ReadyNAS has a backup button.)

Figure 4-3

Note: Backup jobs cannot go past midnight to the next day. Set a backup job start stop

time that does not traverse midnight.

ReadyNAS 3200 Software Manual

4-6 Securing Your Data

v1.0, June 2009

Step 4 – Choose Backup Options

In this last step, you can set up how you want backups to be performed. To set up a backup
schedule:

1. Schedule a full backup. Select when you want full backups to be performed. You can elect to

do this just the first time, every week, every 2 weeks, every 3 weeks, every 4 weeks, or every
time this backup job is invoked.

The first full backup is performed at the next scheduled occurrence of the backup depending
on the schedule you specify, and the next full backup is performed at the weekly interval you
choose calculated from this first backup. Incremental backup is performed between the full
backup cycles.

Backups of a Web or FTP site only have the option to do a full backup every time.

2. Send a backup log. Backup logs can be sent to the users on the Alert contact list when the

backup is complete. It is a good idea to select this option to make sure that files are backed up
as expected. You can elect to send only errors encountered during backup, full backup logs
consisting of file listings (can be large), or status and errors (status refers to completion status).

3. Remove files from backup destination. Select if you want to erase the destination path

contents before the backup is performed. Be careful not to reverse your backup source and

Figure 4-4

destination as doing so can delete your source files for good. It is safer to not select this option
unless your device is running low on space. Do experiment with a test share to make sure you
understand this option.

4. Remove deleted files on backup target for rsync. By default, files deleted in the backup

source will not get deleted in the backup destination. With rsync, you have the option of
simulating mirror mode by removing files in the backup destination deleted from the backup
source since the last backup. Select this option if you wish to do this. Experiment with a test
share to make sure that you understand this option.

5. Change ownership of backup files. The Backup Manager attempts to maintain original file

ownership whenever possible; however, this might cause problems in Share Security mode
when backup files are accessed. To work around this, you have the option of automatically
changing the ownership of the backed-up files to match the ownership of the share. This
allows anyone who can access the backup share to have full access to the backed-up files.

6. Click Apply to save your settings.
Before trusting your backup job to a schedule, it is a good practice to manually perform the back up

to make sure that access to the remote backup source or destination is granted, and that the backup
job can be done within the backup frequency you selected. This can be done after you save the
backup job.

Viewing the Backup Schedule

After saving the backup job, a new job appears in the Backup Schedule section of the Backup Jobs
screen.

A summary of scheduled backup jobs displays; jobs are numbered beginning at 001.
To manage your backup jobs:

1. Click the Job number icon to modify the selected backup job.

2. Enable or disable job scheduling by selecting/clearing the Enable check box. Disabling the

MAC OS X Time Machine Backup

The ReadyNAS can be used as a back up de stina tion for your OS X Time Machine. After enabling
the Time Machine option, use the “Change Disk...” option from Time Machine Preferences to
select this ReadyNAS. You will need to enter the user name and password specified in the
ReadyNAS when prompted by the MAC for authentication.

Go to http://www.readynas.com/TimeMachine for more information on ReadyNAS support for
Time Machine.

Snapshots

The Volume screen allows you to schedule and take snapshots. You can visualize a snapshot as a
frozen image of a volume at the time you take the snapshot. Snapshots are typically used for
backups, during which time the original volume can continue to operate normally. As primary
storage becomes larger, offline backups tend to become increasingly difficult as backup time

Figure 4-7

ReadyNAS 3200 Software Manual

4-10 Securing Your Data

v1.0, June 2009

increases beyond offline hours. Snapshots allow backups to occur without the need to take your
systems offline.

Snapshots also can be used as temporary backups. For example, if a file on the NAS device
becomes infected with a virus, the uninfected file can be restored from a prior snapshot taken
before the attack.

Taking and Scheduling Snapshots

To take or schedule a snapshot:

1. Click the Snapshot tab panel on the Volume tab page. The Snapshot screen will display.

You can specify how often a snapshot should be taken. Snapshots can be scheduled in intervals
from once every 4 hours to once a week.

2. Specify the frequency and the days that you wish to schedule a snapshot:

Figure 4-8

Note: If you do not see a Snapshot tab within your volume tab, you did not reserve any

space for snapshots when you added the volume. The ReadyNAS 3200 ships with a
snapshot reserved space of 10 GB.

• If you specify a start and end time of 00:00, ReadyNAS will take one snapshot at
midnight. A start time of 00:00 and an end time of 23:00 will set snapshots to be taken
between midnight and 11 pm the next day at the interval you specify. Once you save the
snapshot schedule, the time of the next snapshot is displayed. When the next snapshot is
taken, it replaces the previous one.

• If you prefer, you can manually take a snapshot by clicking Take Snapshot Now.

Figure 4-9

Figure 4-10

ReadyNAS 3200 Software Manual

4-12 Securing Your Data

v1.0, June 2009

You can also specify how long a snapshot should last. If you will be using snapshots for
backups, you can schedule the snapshot to last slightly longer than the expected duration
of the backup. Having an active snapshot can affect the write performance to the
ReadyNAS 3200, so deactivating it when it is not needed might be advantageous in write­intensive environments.

When a snapshot is taken, snapshots of shares appear in your browse list alongside the original
shares, except the snapshot share names have -snap appended to the original share names. For
example, a snapshot taken of a share backup is available as backup-snap.

You can traverse a snapshot share just as you would a normal share except that the snapshot share
is read-only. If you wish, you can select a detailed listing to show the snapshot time in the
Description field.

Snapshots can expire when the reserved snapshot space is filled. The snapshot mechanism keeps
track of data that has been changed from the original volume starting at the point when the
snapshot is taken. All these changes are kept in the reserved snapshot space on the volume. The
Disk space utilization field on the Volume screen shows how much space has been reserved for
snapshots.

Figure 4-11

Figure 4-12

ReadyNAS 3200 Software Manual

Securing Your Data 4-13

v1.0, June 2009

After the snapshot is taken, if changes on the volume exceed this reserved space, the snapshot is
invalidated and can no longer be used.

When the snapshot does become invalidated, an e-mail alert is sent and the status reflected on the
Snapshot screen. The snapshot is no longer usable at this stage.

Resizing Snapshot Space

If you are constantly getting snapshot invalidation alerts, you might want to either increase the
frequency of the snapshot or consider increasing the reserved snapshot space. To do this, or to
eliminate your existing snapshot space (thus increasing your usable volume space), you can
specify the snapshot space you want in the Snapshot Space section. Simply select a value from the
pull-down menu and click Save. Y our snapshot space will be limit ed to the specified percentage of
your volume capacity.

Resizing the snapshot space will occur offline and can take a while depending on your data volume
size and the number of files in your volume. Expanding the snapshot space reduces your data
volume size, and reducing the snapshot space expands it.

Backing Up the ReadyNAS to a USB Drive

The following sections describe how to back up and remove disks from the ReadyNAS systems.

Note: Changes that occupy space in the reserved snapshot space include new file

creation, modifications, and deletions; for instance, any time you delete a 1MB file,
the change caused by the deletion uses up 1MB of reserved space.

Figure 4-13

Note: Because of the way snapshots work, you will encounter a drop in write

performance when a snapshot is active. If your environment requires the highest
throughput in performance, the active snapshot should be deleted, or you should set
a limit on how long the snapshot should be live.

On the ReadyNAS 3200, the Backup button is associated with the USB Port at the front of the
system. By default, the Backup button copies the data from the Backup share onto the USB disk
connected to the USB port at the front of the device. Be mindful of performance impact to users
when backup jobs are run.

You can program backups for one or more predefined backup jobs.

Backing Up to the Web with the ReadyNAS Vault Service

ReadyNAS Vault allows continuous and scheduled backups of your ReadyNAS data to a secure
online Vault. For convenience, the backup data can be managed and accessed wherever you have
Internet access.

To enable the ReadyNAS Vault service, click the link on the ReadyNAS Vault tab page in
FrontView or follow the instructions at: http://www.readynas.com/vault.

Warning: Make sure that you have a USB hard drive attached to the front USB Port

before pressing the Backup button.

v1.0, June 2009

Note that some of the settings suggest that you utilize an Uninterruptible Power Supply (UPS)
before enabling that option:

• Select Enable disk write cache if you want to allow disk write requests to be acknowledged

by the disk before data is written out to the platter. This can give a big boost to write
performance, with a drawback that there is a slight chance that unwritten data in the write
cache will be lost in the event of a power failure.

•The Disable full data journaling improves disk performance at the expense of data

protection. Full data journaling makes a backup of data before writing the data out to the
intended location, providing an extra level of data protection needed to prevent data corruption
for RAID volumes at the expense of disk write performance.

•The Optimize for OS X option provides the best performance in Mac OS X environments

when connected to the ReadyNAS 3200 through the SMB/CIFS protocol. This option,
however, introduces compatibility issues with Windows NT 4.0; do not enable this option if
this device will be accessed by Windows NT 4.0 clients.

•The Enable fast CIFS writes option speeds write performance by enabling aggressive write-

back caching over CIFS. Do not enable this option in multi-user application environments
such as Quick Books where synchronized writes are necessary to keep files in sync.

•The Enable fast USB disk writes option speeds up USB write access by accessing the USB

device in asynchronous mode. If you enable this option, do not remove the USB device
without properly unmounting it. Failure to do so can compromise data integrity on the device.

Adding a UPS

Adding a UPS to the NAS is an easy way to protect against power failures. Simply connect the
ReadyNAS power cable to the U PS, and conn ect the UPS US B monitoring ca ble between th e UPS
and the ReadyNAS. The UPS is detected automatically and shows up in the Status bar. click a
status light to display the status in more detail.

You are notified by e-mail whenever the status of the UPS changes; for example, when a power
failure forces the UPS to be in battery mode or when the battery is low. When the battery is low,
the NAS device automatically shuts down safely.

Power Management

The ReadyNAS 3200 offers power timer (time off/time on), UPS event, and wake-on-LAN power
management options to reduce system power consumption, both while the system is in use and
when it is not in use.

Power Timer

The ReadyNAS 3200 can be scheduled to power off and power back on (on certain models)
automatically. Select the Enable power timer check box and enter the action and time. The
Power ON option does not appear if the ReadyNAS hardware does not support this feature.

Configuring UPS Battery Low Shutdown

If this device is not connected to a UPS device, you may elect to enable a UPS connection to
another NAS device. Select the Enable monitoring of UPS physically attached to a remote
ReadyNAS check box and enter the IP Address in the Remote IP field.

If you use this option, the ReadyNAS is shut down automatically when a battery-low condition is
detected on a UPS connected to another ReadyNAS. This is useful when a UPS is shared by
multiple ReadyNAS units, even though only one ReadyNAS is monitoring the battery status.

As an option, the ReadyNAS can remotely monitor the UPS when connected to a PC running
Network UPS Tools (NUT). For more information about NUT, see

http://www.networkupstools.org.

Wake-On-LAN

You can power-on this device remotely by sending it a “WOL Magic Packet” if the WOL service
is enabled.

Note: When the ReadyNAS 3200 is powered off, any file transfers and backup jobs are

interrupted, and backup jobs scheduled during the power off state do not run.

Note: The ReadyNAS 3200 supports Wake-On-LAN on the first Ethernet interface

(LAN 1) only.
