What is the NETGEAR ReadyNAS?
NETGEAR® ReadyNAS® for Business RAIDiator 4.2.17 network storage products provide
businesses and home users with easy-to-use, high-performance gigabit network attached
storage (NAS) solutions used to share and protect data.
ReadyNAS systems enable users across the LAN, or WAN, or over the Internet to back up
and share data from Windows, Macintosh, and Linux systems.
Offering extensible, high-availability data protection, ReadyNAS systems come with robust,
fail-safe features that can include:
• ECC memory that safeguards data from single-bit errors in memory (3100, 3200,
4200)
• Support for RAID 0, 1, 5, and 6, plus hot spare (RAID 6 on Pro, 3200, and 4200)
• Dual redundant Gigabit Ethernet ports
• NETGEAR’s proprietary X-RAID2TM for automatic volume expansion
• Redundant power supplies (3100, 3200, and 4200)
In addition to providing NAS functionality, on selected ReadyNAS units you can set up iSCSI
volumes so that the ReadyNAS can simultaneously act as a SAN (storage area network).
Your ReadyNAS continually monitors the entire system for abnormal situations or failures.
Status indicators provide quick hardware and software status readings, and email alerts
inform you about critical events in the system.
Additionally, with the FrontView Management Console, the ReadyNAS can be customized
with a wealth of add-on features developed by NETGEAR, NETGEAR’s partners, and the
ReadyNAS development community.

RAIDar Utility
RAIDar is a discovery tool that recognizes ReadyNAS devices on your network and enables
easy setup and management of all your ReadyNAS units. Install it on a computer that is
connected to the same local area network (LAN) as your ReadyNAS unit. The RAIDar utility
is included on the Resource CD that came with your unit. It includes versions for Windows,
Mac, and Linux operating systems. It is also available at
Launch the RAIDar utility. It automatically finds the device or devices on the network without
needing their IP addresses, and makes it easy to see the status of your units. You should see
your ReadyNAS device or devices listed.
The default IP configuration is set to DHCP; if the unit does not get an IP address, it defaults
to 192.168.168.168.

From the IPv4 drop-down menu, select Use values from a DHCP server or Use values
below:
• Use values from a DHCP server
In most networks where a DHCP server is enabled, you can specify the Use values
from a DHCP server option to automatically set the IP address and network mask. 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 or router to a value of at least
1 day . Otherwise, you might notice that the IP address of the unit changes even when
it has been turned off for only a few minutes. Most DHCP servers allow you to map a
static IP address to a MAC address. If you have this option, this ensures that your
ReadyNAS maintains the same IP address, even in DHCP mode.
• Use values below
If you assign a static IP address by selecting Use values below, be aware that the
browser will lose connection to the ReadyNAS device after the IP address has been
changed. To reconnect after assigning a static IP address, open the RAIDar utility,
click Rescan to locate the device, and then reconnect.
Also note that you must take care to correctly enter the IP address. If you enter an
incorrect IP address, you cannot connect to your ReadyNAS system. To recover from
an incorrectly entered IP address, you must perform an OS reinstall reboot. For more
information, see the appropriate hardware manual for your system:
• ReadyNAS Ultra, Ultra Plus and Pro Series Hardware Manual
• ReadyNAS Rack-Mount Hardware Manual
These manuals are available at http://readynas.com/documentation.
From the IPv6 drop-down menu, select Use values from a DHCP server or Use values
below:
• Configure Automatically
In most networks where a DHCP server is enabled, you can specify the Configure
Automatically option to automatically set the IP address and network mask. If you
elect to assign the IP address automatically , values are obtained from a DHCP server .
In this case, NETGEAR advises that you set the lease time on the DHCP server or
router to a value of at least 1 day. Otherwise, you might notice that the IP address of
the unit changes even when it has been turned off for only a few minutes. Most DHCP
servers allow you to map a static IP address to a MAC address. If you have this
option, this ensures that your ReadyNAS maintains the same IP address, even in
DHCP mode.
• Use values below
If you assign a static IP address by selecting Use values below, be aware that the
browser will lose connection to the ReadyNAS device after the IP address has been
changed. To reconnect after assigning a static IP address, open the RAIDar utility,
click Rescan to locate the device, and then reconnect.

Speed/Duplex Mode
NETGEAR advises that you keep the setting in an Auto-negotiation mode; however, if you
have a managed switch that works best when the devices are forced to a particular speed or
mode, you can select either the full-duplex or half-duplex setting as needed.
MTU
NETGEAR advises that you leave the default setting; however, in some network
environments, changing the default MTU value can fix throughput problems.
Teaming/Failover
You can use this area to combine two or more Ethernet interfaces into one. This allows your
ReadyNAS to pool the bandwidth provided by multiple Ethernet interfaces for use with one IP
address, potentially improving performance. This feature is called teaming. To use teaming,
your Ethernet cables must be connected to the same network switch and your network switch
must support teaming.
Another benefit of combining two or more Ethernet interfaces is that failover is supported.

ReadyNAS offers several options for teaming.
Note that the option you select might affect ReadyNAS network performance. On ReadyNAS
systems that support both 1GbE and 10GbE interfaces, avoid mixing different speeds within
a team to prevent performance fluctuation.
• Round-Robin.
Transmits 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 team is active.
A different interface becomes
active if, and only if, the active interface fails. The team’s MAC address is externally
visible on only one port to avoid confusing the switch.
• XOR.
Transmits based on the default simple transmit hash policy. This mode provides
load balancing and fault tolerance.
• Broadcast.
Transmits 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

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 traf
fic and does not require any special switch support. The receive load
balancing is achieved by ARP negotiation.
VLAN Settings
Use this section to specify whether or not to allow devices residing on different segments of a
LAN (Virtual Local Area Network), 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.
Managing Y our ReadyNAS System
21
Page 22
ReadyNAS for Business RAIDiator 4.2.17
If you want to use the ReadyNAS in a VLAN environment, select the Enable VLAN support
check box, and enter a numeric VLAN ID. This requires a reboot of the ReadyNAS for the
VLAN function to take effect.
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.
Performance Settings
The Enable jumbo frames option allows you to optimize the ReadyNAS for large data
transfers.
Use this option only if your NICs and your gigabit switch support jumbo frames. The
ReadyNAS supports up to a 9000 byte frame size. For optimal performance, a switch
capable of this frame size or larger should be used.

Global Network Settings
Hostname
The hostname you specify is used to advertise the ReadyNAS on your network. You can use
the hostname to address the ReadyNAS in place of the IP address when accessing the
ReadyNAS from Windows, or over OS X using SMB. This name also appears in the RAIDar
scan list.
The default hostname is nas- followed by the last 3 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 DSL service.
If you selected the DHCP option in the Ethernet screen, the default gateway field is
automatically populated with the setting from your DHCP server
option, you can manually specify the IP address of the default gateway server here.
. If you selected the static
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.
If you selected the DHCP option in the Ethernet screen, 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 Windows Internet Naming Service (WINS) server allows the ReadyNAS or other devices
on the network to be browsed from other subnets. This is useful if you want to browse by
hostname across multiple subnets (for example, over VPN.
You can specify the WINS server IP address, or 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 screen allows
you to specify your ReadyNAS as a DHCP server.
Select the Enable DHCP service check box to make the ReadyNAS device act as a DHCP

WARNING!
These options are available only if the 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 want to
use this device as a DHCP server, make sure to specify static
addresses in the Ethernet and DNS tabs.

Route
Use the Route screen to specify a manual routing table for each Ethernet interface and to
optimize performance.
For example, you could configure a manual routing table to assure that these Ethernet
interfaces are directly routed over a fiber backbone and assure the unit does not experience
the traffic congestion that can build up on a gigabit segment.

• Updating the Admin Password on page 26.
• Security Access Modes on page 27.
• Accounts on page 27.
Updating the Admin Password
The Admin Password screen allows you to change the administrator user password. The
administrator user is the only user who can access the FrontView Management Console, and
has administrative privileges when accessing shares.
Note: Be sure to set a password different from the default password and
keep it in a safe place. Anyone who obtains this password can
change settings or erase data stored on the ReadyNAS.
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.

Page 29
ReadyNAS for Business RAIDiator 4.2.17
CIFS (Common Internet File Service)
Sometimes referred to as SMB, CIFS is used mainly by Microsoft Windows clients, and
sometimes by Mac OS X clients. Under Windows, My Network Places and Network
Neighborhood uses CIFS. This service is enabled by default.
NFS (Network File Service)
NFS is used by Linux and Unix clients. Mac OS 9/X users can access NFS shares through
console shell access. ReadyNAS supports NFS v3 over UDP and TCP.
AFP (Apple File Protocol)
Mac OS 9 and OS X work best using this protocol because it handles an extensive character
set. However, in a mixed PC and Mac environment, NETGEAR recommends CIFS/SMB over
AFP, unless enhanced character set support is necessary for the Mac. ReadyNAS supports
AFP 3.2.
FTP/FTPS (File Transfer Protocol and FTP with SSL encryption)
Widely used in public file upload and download sites. ReadyNAS supports anonymous or
user access for FTP clients, regardless of the security mode selected. You can elect to set up
port forwarding to nonstandard ports for better security when you access files over the
Internet. Alternately, use an FTPS client for secure and encrypted login and data transfers.
HTTP (Hypertext Transfer Protocol)
ReadyNAS supports HTTP file manager, allowing read/write access to shares using the
browser. This service can be disabled in lieu of HTTPS to allow for a more secure
transmission of passwords and data. With the redirect option, access to http://readynas_ip
can be automatically redirected to a share. This is useful if you do not want to expose your
default share listing to outsiders. To redirect to a share, create an index file, such as
index.htm or index.html, in your target share. You can also enable or disable 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. If you want remote Web access to FrontView or your HTTPS shares, specify
a nonstandard port (the 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 use to
address ReadyNAS. This allows you to bypass the default dummy certificate warnings
whenever users access the ReadyNAS over HTTPS.
Rsync
Rsync is an extremely popular and efficient form of incremental backup made popular on the
Linux platform, but is now available for various other Unix systems, as well as Windows and
Mac. Enabling Rsync service on the ReadyNAS allows clients to use Rsync to initiate
backups to and from the ReadyNAS.

Understanding Volume Management
The ReadyNAS family offers the following volume technologies:
• X-RAID2 on page 41.
• Flex-RAID on page 43.
• USB Volumes on page 50.
• iSCSI Volumes on page 52.
X-RAID2
X-RAID2TM is the NETGEAR auto-expandable RAID technology that
allows you to expand your ReadyNAS capacity by adding additional
disks, or replacing existing disks with higher capacity disks.
With X-RAID2, you do not need to know intricate details about RAID, except that as you need
more space, your volume can grow without the need to reformat your drives or move your
data to another location. Because the expansion happens online, you can continue to use the
ReadyNAS while the underlying volume capacity increases.
In addition, if your six-bay or larger ReadyNAS unit is in X-RAID2 mode, you can configure it
to use added disks to expand storage space or to increase data protection.
To expand storage space when adding drives, in the Next added drive section, select the
Will be used to expand volume radio button. To increase data protection when adding
drives, select the Will be used to add dual redundancy radio button.
Note: The Next added drive section does not display for ReadyNAS units
with fewer than six drive bays.
Adding a Second Disk for Redundancy
With only one disk in your ReadyNAS, the X-RAID2 volume has no redundancy , and provides
no protection from disk failure. However, if and when you feel the need for redundancy, add a
new disk with at least the same the capacity as the first disk. You can elect to power off the
ReadyNAS and add the disk, or you can hot-swap the disk while the ReadyNAS is online.
Managing Y our ReadyNAS System
41
Page 42
ReadyNAS for Business RAIDiator 4.2.17
Depending on the size of the disk, within a few hours, your data volume will be fully
redundant. Since the process occurs in the background, you can continue to use the
ReadyNAS without interruption.
Adding More Disks
At a certain point, you will want more capacity. With typical RAID volumes, you have to back
up the data to another system (with enough space), add a new disk, reformat the RAID
volume, and restore the data back to the new RAID volume.
With X-RAID2, add the third disk using the ReadyNAS hot-swap disk tray. When adding
multiple disks at the same time, power down the ReadyNAS, add the disk(s), and turn the
unit back on. The X-RAID2 device initializes and scans the newly added disk(s) for bad
sectors. This is done in the background, so you can continue using the ReadyNAS while the
expansion proceeds. An email notice is sent when the volume has completed the expansion.
Replacing Disks for More Capacity
When more space is needed, but you are unable to install additional disks, you can still
expand the volume capacity by replacing the existing disks with higher capacity disks.
The ReadyNAS supports hot-swapping, so you can swap disks without turning off the unit.
Simply replace the first disk, and the ReadyNAS synchronizes the disk with data from the
removed disk. This process can take 30 minutes or longer, depending on disk capacity, but
you can continue to use the ReadyNAS while the new disk synchronizes. Upon completion,
replace the second disk with another higher capacity disk, and allow that disk to synchronize.
X-RAID2 expands the volume when a minimum of two disks are replaced. When you have
replaced the number of disks you want to replace (minimum of two), reboot the ReadyNAS to
initiate the background expansion. An email notice is sent when the volume has completed
the expansion.
Changing RAID Modes
X-RAID2 is the default technology used by ReadyNAS. However, for a more flexible option,
you can set ReadyNAS to Flex-RAID mode. This option allows you to assign a standard
RAID level so you specify a hot spare, and create multiple volumes.
The process involves setting the ReadyNAS back to Factory Default and using RAIDar to
configure the volume during a 10-minute delay during boot.
WARNING!
Setting the ReadyNAS to the factory default will erase all data.
For instruction on how to change RAID modes, see Changing between X-RAID2 and
Flex-RAID Modes on page 48.
For more about RAID, X-RAID2 and Flex-RAID, see Appendix A, Understanding RAID.

Flex-RAID
Flex-RAID technology utilizes the industry-standard RAID levels 0, 1, 5, 6 (on units with at
least 6 drive bays), and 10 (on units with at least 4 drive bays).
Flex-RAID advantages include:
• The default volume can be deleted and re-created, with or without snapshot reserved

Reconfigure Volume C
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 process involves these high level steps:

WARNING!
Make sure that you back up the files you want to keep before

Adding a Volume
After deleting the volume, the Add Volume screen shows the available configurable space
on the physical disks. All disks are selected by default, and you can specify a hot spare disk
if you want. 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.

3. Specify the reserve space for a snapshot. Next, select the percentage of the volume you
want to allocate for snapshots. You can specify 0 if you want 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, 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 the example, 10 percent of the volume will be reserved for
snapshots.
If you do not reserve space for snapshots, the snapshot screen is not displayed in the
olume screen.

4. Specify the volume size. After you specify the volume parameters, enter the appropriate
volume size if you want 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 you reboot, an email notification is sent when the volume has been added. Use the
RAIDar utility to reconnect to the ReadyNAS device.
RAID Settings
After a volume is added, return to the V olume screen and click the RAID Settings screen to
display the current RAID information and configuration options for the volume.
Notice that the disk on Channel 4 that was not configured in the example is listed in the
Available Disks section. To add this disk as a hot spare click Make hot spare.
To remove a disk from the volume, click Remove. The volume will still be available but in a
non-redundant state. An additional disk failure would render this volume unusable.

When the USB device is unmounted, you have the option of renaming it. The next time the
same device is connected, it uses the new name rather than the default USB_FLASH_n or
USB_HDD_n naming scheme.
The USB storage shares are listed on 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. To change the
base device name select Volumes > USB Storage.
USB Flash Device Option
Toward the lower portion of the USB Storage screen is the USB Flash Device Option
section, where you can elect to copy the content of a USB flash device to a specified share
on connection. Files are copied to a unique timestamp folder to prevent existing data from
being overwritten. This is useful for uploading pictures from digital cameras and music from
MP3 players without a PC.
In User Security mode, an additional option to set the ownership of the copied files is
available.
USB Volume Name and Access Rights
USB volume name and share access settings are persistent across mounts. The ReadyNAS
attempts to remember the name as long as there is a unique ID associated with the USB
device so that the next time the device is connected, the same share name or names will be
available. Share access restrictions are saved across disconnects.
Note: Even when access authorization is based on user login, files on a
USB device are saved with UID 0, regardless of the user account.
This allows easy sharing of the USB device with other network
storage and PC systems.

iSCSI Volumes
Use the iSCSI service to create one or more iSCSI volumes on the ReadyNAS.
Note: iSCSI is not available on the ReadyNAS 1500.
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
(SAN) protocol, allowing organizations to consolidate storage into data 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 attached disk to the client system
acting as the iSCSI initiator
target device, and treat the device as though it was locally attached.
. Windows, for instance, could run FAT32 or NTFS on the iSCSI
Area Network
To configure an iSCSI target volume on the ReadyNAS, select ViSCSI.
To enable iSCSI support, click Create iSCSI Target, and enter the name of the target you
want, and the capacity you want to reserve for this target device. Maximum capacity is
slightly less than the full free space on the ReadyNAS. If you want 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.

Setting Security Access Modes
The ReadyNAS offers the User and Domain security access options.
Select the appropriate option based on the required level of security and your current network
authentication scheme.
User
NETGEAR recommends user security mode for the small and medium-size office or
workgroup environments. User mode allows you to set share access restrictions based on
user and group accounts. In this security mode, the administrator must set and maintain user
and group accounts on the ReadyNAS device itself. See User Security Mode on page 55 for
more information about using this option.
Domain
The Domain security mode is appropriate for department or corporate environments where a
centralized Windows-based domain controller or active directory server is present.
ReadyNAS device integrates into this environment by creating a trusted relationship with the
domain or ADS authentication server and allowing all user authentications to occur there.
This eliminates the need for separate account administration on the device itself. See
Domain Security Mode on page 56 for more information about using this option.
The

User Security Mode
This mode is ideal for small and medium-size offices or workgroups. Select the User security
option to control access to shares based on user or group accounts and if your network does
not utilize a domain controller for authentication.
In User security mode, the administrator specifies a workgroup name, and creates user and
group accounts, and has control over how much disk space is allocated for each user or
group. A user account needs to be created for anyone accessing this device. This option
supports setting disk quotas on a per-user or per-group basis.
Each user is given a home share on the ReadyNAS device so personal data remains private.
This home share is accessible only by that user
backups. The option to automatically generate the private home share is controlled in the
Accounts/Preferences screen, and can disabled as needed.
Note: Private home shares are accessible only by users using CIFS
(Windows), AFP (Mac), and FTP/S protocols.
You need the following information to set up the ReadyNAS for User security mode:

Domain Security Mode
For the Domain security 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 device. At this time ReadyNAS can be used in a domain environment that serves
up to 32,000 users.
You need the following information to set up the ReadyNAS for Domain security mode:
• Domain name
• Domain administrator login
• Domain administrator password

You can elect to have the ReadyNAS automatically auto-detect the domain controller, or you
can specify the IP address. If the auto-detection fails, you need to supply the IP address of
the domain controller to join the domain.
Note: If there are a large number of users in your domain, the FrontView
management system might slow to an unusable state. To help
performance, you might want to clear the Display users from trusted domains... check box.
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 pulls the account
information from the controller and displays it on the Accounts screen if you have the Display users from trusted domains… option enabled. If you want, you can assign a disk quota to
the domain users and groups. If email addresses are specified, users are automatically
notified when approaching and reaching their quotas.

Importing Group Lists
A user can belong to multiple groups. Once user accounts are created, you can place users
in secondary groups. 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 the Marketing and Sales groups.
While adding a new group, specify the amount of disk space you want to allocate to that
group by setting a disk quota. A value of 0 denotes no limit. You can also set the Group ID,
(GID), of the group that you are adding. You can leave this field blank and let the system
automatically assign this value unless you want to match your GID to your NFS clients.
You can view or change your groups by clicking the alphabetical index screen, or click All to
list all groups.
To add a large number of groups, select Import group list from the pull-down menu, and
browse to locate the file containing the group list. You can upload a CSV (comma-separated
values) formatted file containing the group account information.
• GID is automatically generated if not specified.
• Empty fields are replaced with account defaults.
• Group members are optional.
Examples of acceptable formats are as follows. Note that you can omit follow-on commas
and fields if you want to accept the system defaults for those fields, or you can leave the
fields empty:
flintstones
In this example, the group flintstones is created with an automatically assigned GID and
default quota.
rubble,1007,5000,barney:betty
In this example, the group rubble has a GID of 1007, a quota of 5000Mb, with members
barney and betty.

This chapter discusses managing and accessing data from the following operating systems and
protocols, and contains the following sections:
• Managing Shares
• Accessing Shares from a Web Browser
• Accessing Shares from Windows
• Accessing Shares from Mac OS X
• Accessing Shares from Mac OS 9
• Accessing Shares through FTP/FTPS
• Accessing Shares from Linux/Unix

Managing Shares
Shares enable you to organize the information stored on a volume. The administrator has
access to that information and sets permissions for other users and groups. For example, for
generic policies and forms, like blank expense reports, everyone should be able to access
them. For sensitive data, like financial information, only the finance group and specified
personnel should be granted access to it.
The Shares screen provides share service options for the ReadyNAS device, which includes
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 Shares >
If more than one volume is configured, click the volume where you want to add the share.
2. Enter the share name and description.
Once you finish adding the shares, they will be accessible from different client operating
systems, as described later in this chapter
Add Shares.

Note: Enabling public access means anyone on the network without a
user account on the ReadyNAS can access the share.

Share Access Restriction
To limit share access to particular users or groups, 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, to allow read-only access to all, and read/write access only to user fred and
group engr, set the following:
• Default: Read-only
• W
rite-enabled users: fred
• W
rite-enabled groups: engr
To limit this access only to hosts 192.168.2.101 and 192.168.2.102, set the following:
To grant guests access to this share, select the Allow guest access check box.

Share Display Option
Restricting access to a share does not prevent users from seeing the share in the browse list.
In certain instances, such as backup shares, you might want to prevent users from seeing it.
To hide a share, select the Hide this share check box. Users with 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
A Recycle Bin can be enabled for each share for Windows users. Use the Enable Recycle
Bin option is shown at the bottom of the CIFS screen.
When this check box is selected, whenever a file is deleted, 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 the grace period by setting how long to keep the files in the Recycle Bin and
how large the Recycle Bin can get before the files are 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 for newly created files is
read/write for the owner, and owner’s group, and read-only for others (that is, everyone).
Permission for newly created folders is read/write for everyone. The default permission can
be changed to meet additional security requirements.
Opportunistic locking, often referred to as oplocks, enhances CIFS performance by allowing
files residing on the ReadyNAS to be cached locally on the Windows client with the file or files
opened, thus eliminating network latency when the files are constantly accessed.
When another client attempts to open the same file or files, the cached data is written to the
ReadyNAS, and the oplock is released.

Advanced Options
Clicking the access icons on the Share LIst screen opens the Advanced Options screen,
which offers advanced low-level file manipulation options that can affect file access through
all file protocol interfaces. Care should be taken before these options are used, 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 select the Grant rename and delete privilege to non-owners option. In a
collaborative environment, you might want to enable this option. In a more security-conscious
environment, disable this option.
Advanced Share Utilities
Use this option to adjust the timestamps of the contents of the share. This can be used to fix
issues with incremental backups, and sources or destinations that change local timestamps
when daylight savings time changes. In the Shift share content timestamps by field enter a
positive number to push timestamps ahead, negative numbers to push them back.

hostname starts with nas- followed by the last three hex bytes of the device MAC address.
To access a specific share, simply add the name of the share to the address.
For example, http://<hostname>/backup
For a secure encrypted connection use HTTPS. You are prompted to log in.

One useful application for a Web share is to set an internal company Web site. 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) on the Web site can be
viewed from any Web browser.
Note: Files created under the Web file manager can be deleted only under
this file manager. The only exception is for the admin user. The
admin user can change or delete any files created over the Web
using any protocol. Files not created from the file manager can be
modified within the file manager, but cannot be deleted here.

Configuring Backup Jobs
The Backup Manager integrated with the ReadyNAS allows the ReadyNAS to act as a
powerful backup appliance. Backup tasks can be controlled directly from the ReadyNAS
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 can act as a
simple central repository for both home and of
ReadyNAS systems, you can set up one ReadyNAS to directly back up another.
Adding a New Backup Job
You can use the following backup sources:
• A public or a private home share
• An iSCSI individually addressable (logical) SCSI device (a logical unit number or
LUN)
• All home shares on the ReadyNAS
fice environments. And with multiple
Note that backup sources can be local or remote.
To create a new backup job:
1. From the main menu, select Backup >
The Add a New Backup screen displays.
2. Select a backup source.
The backup source can be a share or a path located locally on the ReadyNAS, or
remotely on another ReadyNAS or a computer
share on the ReadyNAS or a USB device attached to the ReadyNAS, or you back up the
entire data volume.
Add a New Backup.
. If the source is local, you can select any
If you select a share or a USB device on the ReadyNAS, you can leave the path blank to
back up the entire share or device or enter a folder path to back up just the content of that
folder.
Backing Up Y our Data
89
Page 90
ReadyNAS for Business RAIDiator 4.2.17
If you want to back up a remote source to the ReadyNAS, enter the remote host name,
the folder path, and any login credential required to access that path.
To ensure that you have the right access to the remote backup source, click Test Connection after entering the source parameters.
Each file protocol uses a slightly different path notification, so refer to the following list for
the correct form. Notice that a forward slash (/) is used instead of a backslash (\) in all
instances. Depending on how your unit is configured, you are presented with several
backup source options:
• Remote Windows/NAS (Timestamp). Backs up a share from a Windows PC.
Incremental backups use timestamps to determine whether files should be backed
up. Examples of a Windows or remote ReadyNAS path:
• /myshare
• /myshare/myfolder
• Remote Windows/NAS (Archive Bit). Backs up a share from a Windows PC.
Incremental backups use the archive bit of files, similar to Windows, to determine if
they should be backed up. Examples of a Windows or remote ReadyNAS path:
• /myshare
• /myshare/myfolder
• Remote Website. Backs 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. Examples of a web site path:
• /myshare
• /myshare/myfolder
• Remote FTP Site. Backs up an FTP site or a path from that site. Examples of an FTP
path:
• /myserver/mypath/mydir
• /myserver/mypath/mydir/myfile
• Remote NFS Server. Backs up from a Linux or UNIX server across NFS. Mac OS X
users can also use this option by setting up an NFS share from the console terminal.
Examples of an NFS path:
• /mypath
• /mypath/myfolder
• Remote Rsync Server . Backs up from a Rsync server . Rsync was originally available
for Linux and other UNIX-based operating systems, but is also popular under
Windows and Mac for its efficient use of incremental file transfers. This is the

preferred backup method between two ReadyNAS devices. For more information,
see Enabling Rsync and Specifying Rsync Rights on page 103.
When you select the Remote Rsync Server as your backup source, you are
presented with additional options:
• Tunnel Rsync over SSH. Enables Rsync data transfers to go through a secure,
encrypted SSH tunnel. This is recommended when backups are being transferred
over the Internet. To use this option, you will need to download the public SSH file
key from the ReadyNAS and add it to the remote Rsync server’s authorized SSH
key list. To download the key, click Download public SSH key.
If the destination Rsync server is a ReadyNAS, select Shares > Share Listing on
the Rsync screen, and click Manage SSH Keys to add the public key
.
For more information about using Rsync with SSH, see the article Setting up Rsync over SSH at http:/readynas.com/rsync_ssh.
• Enable Compression. Compresses data before transferring.
This option is
especially useful for slower network connections, such as when transferring data
over a WAN.
• Remove deleted files from target. Ensures that the destination has exactly the
same image as the ReadyNAS; however
, it is important to understand that any
accidental deletion of data on the ReadyNAS cannot be recovered.
• File and directory exclusion list. Specify any files and directories that you want
to exclude from the backup. Enter the files and directories as a comma-separated
list.
• iSCSI. Backs up from an iSCSI source.
3. Select a backup destination.
Backing Up Y our Data
91
Page 92
ReadyNAS for Business RAIDiator 4.2.17
This step is similar to Step 1 except you are now specifying the backup destination. If you
selected a remote backup source, you need to select a destination on the ReadyNAS.
The list of backup destination options is dependent on how your unit is configured. For
example, you must set up an iSCSI target on your unit before iSCSI appears on the
backup destination drop-down menu. Note that either the source or destination must be
the ReadyNAS.
If the source is the ReadyNAS, you can either enter a ReadyNAS destination or you can
specify a remote backup destination.
The remote backup destination can be a remote Windows PC with a ReadyNAS system,
a remote FTP site, a remote NFS server, a remote Rsync server, a ReadyNAS share, or a
USB device.
Note: You can select Rsync for a remote ReadyNAS if it is configured to
serve data over Rsync.
4. Set a 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 instantaneous) and perform
backups of those snapshots.
Backing Up Y our Data
92
Page 93
ReadyNAS for Business RAIDiator 4.2.17
If you want, you can elect not to schedule the backup job so that you can invoke it
manually instead by clearing the Perform backup every check box. You might want to
do this if your ReadyNAS has a backup button, and if you prefer to tie the job to the
button.
5. Choose backup options.
Set how you want the backups to be performed:
• Schedule a full backup.
To set the frequency with which full backups are performed,
select from these options:
• First time
• Every week
• Every 2 weeks
• Every 3 weeks
• Every 4 weeks
• 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
. The next full backup is performed at the
interval you choose calculated from this first backup. Incremental backups are
performed between the full backup cycles.
Backups of a web or FTP site have only the option to do a full backup every time.

• 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).
Note: Backup log emails are restricted to approximately 10K lines. T o view
the full backup log (regardless of length), select Status > Logs and
click the Download All Logs link.
• Remove files from backup destination. Select this option if you want to erase the
destination path contents before the backup is performed. Be careful not to reverse
your backup source and destination because 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 an experiment with a test share to make sure you understand this option.
• 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.
Note: Before trusting your backup job to a schedule, it is a good practice to
manually perform the backup 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 Log
You can view the backup log while the job is in progress or after it has finished.
The log format might differ depending on the backup source and destination type that was
selected, but you can see when the job was started and finished, and whether it was
completed successfully or with errors.
Editing a Backup Job
To edit a backup job, either click the three-digit job number button on the Backup Jobs
screen, or click the Edit Backup Job link while viewing that job log. Make appropriate

Snapshots
The V olume screen allows you to schedule and take snapshots. Think of 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 continues to operate normally. As primary
storage becomes larger, offline backups tend to become increasingly difficult because
backup time increases beyond offline hours. Snapshots allow backups to occur without the
need to take your systems offline.
Snapshots can also be used as temporary backups. For example, if a file on the ReadyNAS
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. From the V
Specify how often a snapshot should be taken. Snapshots can be scheduled in intervals
from once every 4 hours to once a week.
Note: If you do not see a Snapshot screen on the V olume screen, you did
olume screen, click the Snapshot screen to display the Snapshot screen.
not reserve any space for snapshots when you added the volume.
The ReadyNAS ships with a snapshot reserved space of 10GB. For
information on how to reserve space for snapshots, see Resizing
Snapshot Space on page 101.

2. Specify the frequency and the days that you want to schedule a snapshot:
When start and end times are set to 00:00, ReadyNAS takes one snapshot at midnight. A
start time of 00:00 and an end time of 23:00 sets snapshots to be taken between midnight
and 1
1 p.m. the next day at the interval you specify.
Once you save the snapshot schedule, the time of the next snapshot displays. When the
next snapshot is taken, it replaces the previous one.
You can take manual snapshots at any time by clicking the T ake snapshot now button.
Take snapshot
now button
You can also specify how long a snapshot should last. If you use snapshots for backups,
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, so
deactivating snapshots when not needed might be advantageous in write-intensive
environments.

When a snapshot is taken, a duplicate snapshot appears in the browse list alongside the
original share, except the duplicate share name has -snap appended to the original share
name. For example, a snapshot taken of the share music is available as music-snap.
Y ou can traverse a snapshot share just as you would a normal share except the snapshot
share is read-only. 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.
After the snapshot is taken, if changes on the volume exceed this reserved space, the
snapshot is invalidated and can no longer be used.
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.
When the snapshot becomes invalidated, an email alert is sent and the status reflected
on the Snapshot screen.
The snapshot is no longer usable at this stage.
