FrontView Advanced Control
The Advanced Control mode offers the all settings available in the Setup Wizard plus more.
When you first switch to this mode, you’ll see the menus on the left that allow you to quickly jump to the desired menu page. Towards the bottom left, you’ll notice buttons that allow you to switch back and forth between the Setup Wizard mode and the Advanced Control mode.
As you click on the menu buttons, you’ll notice a similar theme across all menu pages. At the top right corner is the command bar which typically provides options to return to the home page, refresh the browser window, display help where available, or to log out of the session. Due to security reasons, the which is necessary to securely log out.
Logout
button only acts as a reminder to close the current browser session
11
At the furthest bottom is the status bar with the date button which doubles its duty as a clock and a link to the Clock page. The status LEDs to the right gives a quick glimpse of the system device status.
The statuses represent:
 Not present
 Normal
– No disk or device attached.
– Device in normal operating mode. If the LED is blinking, this disk is currently re-syncing. During the re-sync process, the performance is temporarily in a “degraded” mode and another disk failure in the volume will render it dead.
 Warning or Dead
 Inactive spare
– The device has failed or requires attention.
– This disk is a “hot spare” on standby. When a disk fails, this disk will
take over automatically.
 Awaiting re-sync
 Life support mode
– This disk is waiting to re-sync to the RAID volume.
– The volume has encountered multiple disk failures and is in the state of being marked dead. However, the ioSafe R4 has blocked it from being marked dead in the event that someone may have accidentally pulled out the wrong disk during runtime. If the wrong disk was pulled out, shutdown the ioSafe R4 immediately, reconnect the disk, and power-on the ioSafe R4. If you reconnect the disk during runtime, the ioSafe R4 will mark it as a newly added disk and you will no longer be able to access the data on it.
 Background task active
– A lengthy background task such as a system update is in
progress.
12
Move the mouse cursor over the LED to display more information on the device, or click on it to display the status in more detail.
Right above the status bar is the action bar. To the left are the Advanced Control and Setup Wizard buttons. To the right is the Apply button. Use this to save any changes in the current menu page.

Network
Ethernet
The Ethernet tab allows you to specify network interface-specific settings.
In the
Standard Setting
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.
box, you can specify the IP address, network mask, speed/duplex mode,
If you assign a static IP address, be aware that the browser will lose connection to the ioSafe R4 device after the IP address has been changed. You can click Rescan in RAIDar to locate the device and reconnect from there.
14
Note
If you elect to assign the IP address using DHCP, it is advisable to set the lease time on the DHCP server/router to a value of at least a day. Otherwise, you may notice that the ioSafe R4 IP address may change 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 ioSafe R4 maintains the same IP address even in DHCP mode.
►
SPEED/DUPLEX MODE
If you have a managed switch that works best if the devices are forced to a particular speed or duplex mode, you can select the desired setting. It’s advisable to keep the setting in auto-negotiation mode otherwise.
►
MTU
In some network environments, changing the default MTU value may fix throughput problems. It’s advisable to leave the default setting otherwise.
►
VLAN SETTING
Virtual Local Area Network, or VLAN, allows devices residing on different segments of a LAN to appear in the same segment, or conversely allows devices on the same switch to behave as though they belong to a different LAN.
If you wish to use the ioSafe R4 in a VLAN environment, select the
Enable VLAN support
checkbox and input a numeric VLAN tag. You will need to reboot the ioSafe R4 for the VLAN function to take effect.
15
Warning
Do not enable VLAN support unless you are sure your clients also support VLAN. Otherwise, you can lose network access to the ioSafe R4 and you may need to perform a firmware re-installation to disable the VLAN setting.
►
PERFORMANCE SETTING
The
Enable jumbo frames
option allows you to optimize the ioSafe R4 for large data transfers such as multiple streams of video playback. Select this option if your NIC and your gigabit switch support jumbo frames.
Note
The ioSafe R4 supports a 7936 byte frame size, so for optimal performance, a switch capable of this frame size or larger should also be used.
Your ioSafe R4 device comes with multiple Ethernet interfaces, you will see a separate configuration tab for each interface.
16
Global Network Settings
►
HOSTNAME
The Hostname you specify is used to advertise the ioSafe R4 on your network. You can use the hostname to address the ioSafe R4 in place of the IP address when accessing the ioSafe R4 from Windows, or over OS X using SMB. This is also the name that will appear in the RAIDar scan list.
The default hostname is
►
DEFAULT GATEWAY
nas-
followed by the last three bytes of your primary MAC address.
The Default Gateway specifies the IP address of the system where your network traffic is routed to if the destination is outside of 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 had selected the DHCP option in the Ethernet tab, the Default Gateway field will be automatically populated with the setting from your DHCP server. If you had selected the Static option, you can manually specify the IP addresses of the default gateway server here.
►
DNS
The DNS box allows you to specify up to three Domain Name Service servers for host name resolution. If you are unfamiliar with DNS, the service translates host names into IP addresses.
17
If you had selected the DHCP option in the Ethernet tab, the domain name server fields will be automatically populated with the DNS settings from your DHCP server. If you had selected the Static option, you can manually specify the IP addresses of the DNS servers and the domain name here.
WINS
The WINS option allows you to specify the IP address of the WINS (Windows Internet Naming Service) server. A WINS server is typically a Windows server on the network that will allow the ioSafe R4 or other devices on the network to be (Windows) browsed from other subnets.
If you do not have an existing WINS server, you can designate the ioSafe R4 to be one. Simply select the
Become a WINS server
checkbox and configure your Windows PC to specify the ioSafe R4 IP address as the WINS server. This can be useful if you wish to browse by hostname across multiple subnets, i.e. over VPN.
18
DHCP
The DHCP tab allows this device to act as a DHCP (Dynamic Host Configuration Protocol) server. DHCP service simplifies management of a network by dynamically assigning IP addresses to new clients on the network.
Click on the
Enable DHCP service
checkbox if you want the ioSafe R4 device to act as a DHCP
server. This is convenient in networks where DHCP service is not already available.
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.
19
Route
The
Route
tab is available if you have two or more network interfaces (Ethernet or Wireless combined) on your ioSafe R4. In some environments, you can optimize your network traffic by manually setting up a routing table.
Route table management is beyond the scope of this manual, and this option is provided only for advanced users who understand routing and wish to deviate from the default routes.

Note
In User or Domain security mode, you can use the admin account to login to a Windows share, and perform maintenance on any file or folder in that share. The admin user also has permission to access all user private home shares to perform backups.
As a safeguard, you will be requested to enter a password recovery question, the expected answer, and an email address. If, in the future, you forget the password, you can go to
https://
ip_address
/password_recovery. Successfully answering the questions there will reset the
admin password, and that new password will be sent to the email address you enter in this tab.
21
Security Mode Selection
The ioSafe R4 device offers three security options for your network environment. Read the quick overview below to help select the most appropriate option based on the required level of security and your current network authentication scheme.
The Share security mode is suitable for most home and small office environments, providing a simple way for people in a trusted environment to share files without the necessity of setting up separate user and group accounts. Shares that you create in this environment can be password­protected if desired.
A more appropriate selection for the medium-size office or workgroup environment is the User security mode. This mode allows you to set up user and group accounts to allow for more specific share access restrictions. 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 may want to restrict company financial data to just users belonging to one particular group. In this security mode, the administrator will need to set up and maintain user and group accounts on the ioSafe R4 device itself. In addition, each user account will be automatically set up with a private home share on the ioSafe R4.
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 ioSafe R4 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. Also, in this security mode, each domain/ADS user will be automatically set up with a private home share on the ioSafe R4.
22
Note
The FrontView management system will slow down in proportion to the number of users in the domain. It is not advisable to use the ioSafe R4 in a domain environment with more than 1000 users.
Share Security Mode
The
Share security mode
►
SPECIFY A WORKGROUP
You only need to specify a workgroup if you wish to change it from the default.
A valid workgroup name must conform to the following restrictions:
is the easiest security option to set up.
 Name must consist of characters a-z, A-Z, 0-9, and the symbols _ (underscore), – (dash),
and . (period).
 Name must start with a letter.
 Name length must be 15 characters or less.
►
SHARE ACCOUNTS
You will notice the Accounts tab which consists of share accounts which match the current share names on the ioSafe R4. These share accounts are listed to allow you the option of changing the UID and quota assigned to the share. The share quota can be changed from the Share Listing in the Share menu as well. The UID does not need to be changed unless you wish to avoid a UID conflict with an existing NFS user.
User Security Mode
In User security mode, you specify a workgroup name just as you would in the previous security option, and create user and group accounts. You will have control over how much disk space is allocated for each user or group.
In this security mode, each user will be given a home share on the ioSafe R4 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 who needs the privilege to perform backups of these private shares. The option to automatically generate the private home share is controlled in the Accounts/Preferences tab, and you can disable it if you wish.
23
Note
Private user shares are only accessible by users using CIFS (Windows) or AppleTalk file protocols.
To set up the ioSafe R4 for this security mode, you will need the following information:
 Workgroup name
 Group names you wish to create (i.e. Marketing, Sales, Engineering)
 User names you wish to create (plus email addresses if you will be setting disk quotas)
 Amount of disk space you would like to allocate to users and groups (optional)
►
SPECIFY A WORKGROUP
To change or set a workgroup name, enter the desired name in the Workgroup field in the User option box. The name can be the workgroup name that is already used on your Windows network.
►
SETTING UP ACCOUNTS
In this security mode, the Accounts tab allows you to manage user and group accounts on the ioSafe R4. A good starting point would be to select the
Manage groups
option from the drop-down box
in the upper right corner.
24
►
MANAGING GROUPS
To add a new group, click on 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.
If desired, 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 can access shares restricted to only
joe
in group
marketing
and
marketing
sales
groups.
also belong to group
sales
so
joe
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 set or change the quota at a later time. 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.
25
After adding your groups, you can view or change your groups by clicking on the alphabetical index tab, or
All
to list all groups.
If you wish to add a large number of groups, select
Import group list
from the selection box.
26
Here, you can upload a CSV (Comma Separated Value) formatted file containing the group account information. The format of the file is:
name1,gid1,quota1,member11:member12:member13 name2,gid2,quota2,member21:member22:member23 name3,gid3,quota3,member31:member32:member33
Please note the following:
 Spaces around commas are ignored.
 The name fields are required.
 Quota will be set to default if not specified.
 GID will be automatically generated if not specified.
 Empty fields are replaced with accounts defaults.
 Group members are optional.
Examples of acceptable formats are as follows (note that you can omit follow-on commas and fields if you wish to accept the system defaults for those fields, or you can leave the fields empty):
flintstones
In this example, group
flintstones
will be created with an automatically assigned GID, and default
quota.
rubble,1007,5000,barney:betty
In this example, group

27
►
MANAGING USERS
To manage user accounts, select the Manage users option in the drop-down box.
To add a user, click on the Add User tab. You can add up to five users at a time.
You can enter a user name, email address, user ID, select a group, password, and disk quota for the user. Only the user name and password fields are required, however, you should specify the user email address if you intend to set up disk quotas. Without an email address, the user will not be warned when disk usage approaches the specified disk quota limit. If you do not wish to assign a disk quota, enter 0.
If you wish to add a large number of users, select
Import user list
from the selection box.
28
Here, you can upload a CSV (Comma Separated Value) formatted file containing the user account information. The format of the file is:

Domain Security Mode
►
DOMAIN/ADS AUTHENTICATION
If you choose the Domain security mode option, you will 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 ioSafe R4 device. You will need the following information:
 Domain name
 Domain administrator login
 Domain administrator password
 If using ADS:
- DNS name of the ADS realm
- OU (Organization Unit). You can specify nested OU's by separating OU entries with commas. The lowest level OU must be specified first.
You can elect to have the ioSafe R4 automatically auto-detect the domain controller, or you can specify the IP address. Sometimes auto-detect will fail, and you will need to supply the IP address of the domain controller to join the domain.
31
If you have a large number of users in your domain, you may need to deselect the
from trusted domains
… checkbox. Otherwise, FrontView management system may slow down
Display users
to an unusable state.
Note
Use of the ioSafe R4 in a domain environment with more than 1000 users is not recommended at this time.
Click Apply to join the domain. If successful, users and groups from the domain will have login access to the shares on this device.
►
SETTING UP ACCOUNTS
Accounts are managed on the domain controller. The ioSafe R4 simply pulls the account information from the controller and displays them in the Accounts tab if you have the

option enabled.
Display
If you wish, you can assign a disk quota to the domain users and groups. If email addresses are specified, users will be automatically notified when approaching and reaching their quotas.

Services
The Services menu allows you to manage various services for share access. This in effect controls the type of clients you wish to allow access to the ioSafe R4.
You will notice three tabs at the top:
Discovery Services
. These different services are explained below.
Standard File Protocols, Streaming Services
, and
Standard File Protocols
The standard file protocols are common file sharing services that allow your workstation clients file transfer to and from the ioSafe R4 using built-in file manager over network file protocols on the client operating system. The available services are:
33
 CIFS
(Common Internet File Service). Sometimes referred to as SMB. This protocol is used mainly by Microsoft Windows clients, and sometimes used by Mac OS X clients. Under Windows, when you click on My Network Places or Network Neighborhood, you’re 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 ioSafe R4 supports NFS v3 over UDP and TCP.
 AFP
(Apple File Protocol). Mac OS 9 and OS X works best using this protocol as it
handles an extensive character set. The ioSafe R4 supports AFP 3.1.
 FTP
(File Transfer Protocol). Widely used in public file upload and download sites. The ioSafe R4 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 non-standard ports for better security when accessing files over the Internet.
 HTTP
(Hypertext Transfer Protocol). Used by web browsers. The ioSafe R4 supports HTTP file manager, allowing web browsers to read and write to shares using the web 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:// http://
iosafe_ip/share
. This is useful if you do not want to expose your share listing to
iosafe_ip
outsiders as well as allowing you to redirect all default web access to a share dedicated to be your website. All you need in the target share is an index file such as
index.html
. You have the option of enabling or disabling login authentication to this
index.htm
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 have the option of specifying a non-standard port 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 address the ioSafe R4. This allows you to bypass the default dummy certificate warnings whenever you access the ioSafe R4 over HTTPS.
to
or
 Rsync
. An extremely popular and efficient form of incremental backup made popular in the Linux platform but is now available for various other Unix systems as well as Windows and Mac. Enabling rsync service on the ioSafe R4 will allow clients to use rsync to initiate backups to and from the ioSafe R4.
Streaming Services
The built-in streaming services on the ioSafe R4 allow you to stream multi-media content directly from the ioSafe R4, without the need to have your PC or Mac powered on.
34
 SquezeCenter
(SlimServer) provides music streaming to the popular Squeezebox music
players from Slim Devices.
 iTunes Streaming Server
enables iTunes clients to stream media files straight from the
ioSafe R4.
 UPnP AV
provides media streaming service to stand-alone networked home media adapters and networked DVD players that support the UPnP AV protocol or are Digital Living Network Alliance (DLNA) standard compliant. The ioSafe R4 comes with a reserved
media
share that is advertised and recognized by the players. Simply copy your media files to the Videos, Music, and Pictures folders in that share to display them on your player. If you wish, you can specify a different media path where your files reside.
35
 Home Media Streaming Server
provides streaming of videos, music, and pictures to popular networked DVD players. The streaming players often utilize the streaming client developed by Syabas. Similar to UPnP AV, this service is used to stream videos, music, and pictures from the reserved
media
share to these adapters. If you wish to change the location where the media files are stored, you can specify a different share and folder path. Note that this path is shared between the UPnP AV and this service.
Discovery Services
 Bonjour Service
provides a simple way of discovering various services on the ioSafe R4. 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 Windows from Apple’s website.
 UPnP
provides a means for UPnP-enabled clients to discover the ioSafe R4 on your LAN.
36
Volumes
Volume Management
The ioSafe R4 consists of two RAID volume technologies – standard RAID levels 0, 1, and 5, and technology. Your system defaults to through a factory default reset process described in
X-RAID
X-RAID
, NETGEAR-patented expandable RAID
, however, you can switch between the two modes
Chapter 4 – System Reset Switch
Flex-RAID
, utilizing the industry-
There are advantages to both technologies.
►
ADVANTAGES OF FLEX-RAID
1. The default volume can be deleted and recreated, with or without the snapshot
reserved space.
2.
Hot spare disk is supported.
3. Full volume management is available – you can create a volume utilizing RAID level 0,
1, or 5, specify the size of the volume, delete a disk from a volume, assign a hot spare, etc.
4. Multiple volumes are supported, each with a different RAID level, snapshot schedule
and disk quota definition.
5. Each disk can be replaced, one by one, then rebuilt; after the last disk is replaced,
another data volume utilizing the newly added capacity can be configured.
.
►
ADVANTAGES OF X-RAID
1. One volume technology, but supports volume expansion, either by adding more disks
or by replacing existing disk with larger capacity disks.
2. You can start out with one disk, and add up to 3 more disks when you need them or
can afford them.
Volume management is automatic. Add a 2nd disk; it becomes a mirror to the 1st. Add
3.
a 3rd, your capacity doubles; add a 4th, and your capacity triples – the expansion occurring while maintaining redundancy.
4.
At a future point in time, each disk can be replaced one by one, have it finish rebuilding, and after the last disk is replaced, your volume automatically expands utilizing the new capacity.
Volume Management for Flex-RAID
If you wish to reconfigure the default volume C, wish to split it into multiple volumes, or specify a different RAID level, you will need to reconfigure your volume. The first step is to delete the existing volume you wish to replace.
37
►
DELETING A VOLUME
To delete a volume, click on the volume tab of the volume you wish to delete or Volume C if only one volume is configured. Make sure if you have data in that volume that you back up the files you wish to keep first. All shares, files, and snapshots residing on that volume
WILL BE DELETED
AND ARE NON-RECOVERABLE!
Click
Delete Volume
You will be asked to confirm your intention by typing:
in the Volume C tab.
DELETE VOLUME
38
►
ADDING A VOLUME
You will then be presented with the
Add Volume
tab listing the available configurable space on the hard disks. All the disks will be selected by default. You can elect to specify a hot spare disk if you wish. A hot spare remains in standby mode and will automatically regenerate the data from a failed disk from the volume. A hot spare disk is only available for RAID level 1 and RAID level 5 if there are enough disks to fulfill the required minimum plus one.
Select Hard Disks
In our example here, we’ll select the first three disks and elect not to specify any of them as a hot spare.
Select RAID level
RAID level determines how the redundancy, capacity utilization, and performance is implemented for the volume. See Appendix A, “RAID Levels Simplified”, for more information. Typically in a three or more disk configuration, RAID level 5 is recommended.
In our example above, we selected RAID level 5 for the three selected disks.
Specify reserve space for snapshot
Next, select the amount of the volume you wish to allocate for snapshots. You can elect to specify 0 if you wish to disable snapshot capability, or you can specify a 5GB increment from 5 to 100GB.
This represents the amount of data you feel would be changing while the snapshot is active. This typically depends on how often you schedule your snapshot (see following section on snapshot), and the maximum amount of data (plus padding) you feel will change during that time. Make sure to
39
allocate enough space for worse case as the snapshot becomes unusable when its reserved space runs out.
In our example above, we selected 50GB of the volume to be reserved for snapshots.
Specify desired volume size
After you’ve specified the above volume parameters, enter the desired 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.
In our example above, we kept the maximum size that was calculated.
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 will then be notified by email when the volume has been added. Use RAIDar to reconnect to the NAS device.
►
RAID SETTINGS
After you have added a volume, you can revisit the Volume tab and click on the
RAID Settings
tab
to display the current RAID information and configuration options for the volume.
Notice 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 on the
Make hot spare
button.
40
We can also remove a disk from the volume by clicking on the
Remove
button. The volume will still be available but in a non-redundant state. An additional disk failure would render this volume unusable.
Warning
The Remove operation is a maintenance feature and is not recommended in a live environment. Its function is equivalent to hot-removing the disk or simulating a disk failure.
The
Locate
Clicking on
option is a way to verify that a disk is correctly situated in the expected disk slot.
Locate
will blink the LED of the disk for 15 seconds.
Volume Management for X-RAID
The X-RAID technology offers a simplified approach to volume management. X-RAID works on the premise that what most people want to do with their data volume over time is either adding redundancy or expanding it without the headaches usually associated with doing that. By using simple rules, X-RAID is able to hide all the complexities yet provide volume management features only previously available in enterprise-level storage solutions.
►
X-RAID REDUNDANCY OVERHEAD
To maintain redundancy from disk failure, X-RAID requires a one-disk overhead. In a two-disk X­RAID volume, the usable capacity is one disk. In a three-disk X-RAID volume, the usable capacity is two disks. In a four-disk X-RAID volume, the usable capacity is three disks.
41
►
X-RAID HAS ONE DATA VOLUME
X-RAID devices only have one data volume. This volume encompasses one to four disks, utilizing the capacity of the smallest disk from each disk. For instance, if you had one 80GB disk and two 250GB disks, only 80GB from each disk will be used in the volume. (The leftover space on the 250GB disks will be reclaimed only when the 80GB disk is replaced with a 250GB or greater capacity disk. See “Replacing All Your Disks for Even More Capacity” below.)
►
ADDING A 2ND DISK FOR REDUNDANCY
A one-disk X-RAID device has no redundancy and provides no protection from a disk failure. However, if and when you feel the need for redundancy, simply power down the device, add a new disk with at least the capacity of the first disk, and power on. 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 ioSafe R4 is not interrupted.
►
ADDING A 3RD AND 4TH DISK FOR MORE CAPACITY
At a certain point, you will want more capacity. With typical RAID volumes, you will have to backup 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.
Not so with X-RAID. Simply power down the device, add the 3rd and perhaps 4th disk and power on. The X-RAID device will initialize and scan the newly added disk(s) for bad sectors in the background. You can continue working normally with the device during this process without any lag in performance. When the process finishes, you will be alerted by email to reboot the device.
During the boot process, your data volume is expanded. This process typically takes about 15-30 minutes per disk, perhaps more, depending on the size of your disks. A 250GB disk takes approximately 30 minutes. Access to the ioSafe R4 is not permitted during this time. You will be notified by email when the process is complete.
After you receive your email, the ioSafe R4 will have been expanded with the capacity from your new disk(s).
►
REPLACING ALL YOUR DISKS FOR EVEN MORE CAPACITY
A couple years down the line, you find the need more disk space, and 1 TB disks are available at an attractive price. Again, you can expand your volume capacity quite easily, although you will need to power down several times to replace your old disks.
First, power down the ioSafe R4, replace the first disk with the larger capacity disk, and boot. The ioSafe R4 will detect that a new disk was put in place and will resync the disk with data from the removed disk. This process will take several hours, depending on disk capacity. The disk will be initialized and scanned for bad sectors first before the resync is started. The total time from the start of initialization to the end of resync can be around 5 hours or more, depending on disk capacity. You will be notified when this resync process is complete.
Upon completion, power down, replace the 2nd disk with another larger capacity disk, and boot. The process will be the same as the 1st disk. You will do this also for the 3rd and 4th disk.
42
Once you get the completion notification for the 4th disk, reboot the ioSafe R4. During boot, volume capacity is expanded with the additional capacity from each disk. For instance, if you had replaced four 250GB disks with four 600GB disks, the capacity of the volume will increase by approximately 350GB x 3 (the fourth disk is reserved for parity). The expansion process will take several hours depending on the capacity expanded, and you will be notified by email when the process is complete. There is no access to the ioSafe R4 during this time.
Changing Between X-RAID and Flex-RAID Modes
You can switch between X-RAID and Flex-X-RAID modes. The process involves setting the ioSafe R4 to factory default and using RAIDar to configure the volume during a 10-minute delay window during boot. Please see
Chapter 4 – System Reset Switch
for more information.
Snapshot
The Volume page offers the ability 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 increases beyond offline hours. Snapshots allow backups to occur without taking systems offline.
Snapshots also can be used as temporary backups as well, perhaps as a means to backup data against viruses. As an example, if a file becomes infected with a virus on the NAS device, the uninfected file can be restored from a prior snapshot taken before the attack.
►
TAKING AND SCHEDULING SNAPSHOT
To take or schedule a snapshot, click on the
Note
Snapshot
tab.
The ioSafe R4 ships with a snapshot reserved space of 0 GB.
In the tab, 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.
43
Specify the frequency and the days that you wish to schedule a snapshot. A start and end-time of 00:00 will take one snapshot at midnight. A start time of 00:00 and end-time of 23:00 will take snapshots between midnight and 11pm the next day at the interval you specify. Once you save the snapshot schedule, the time of the next snapshot will be displayed. When the next snapshot is taken, the previous one is replaced.
If you prefer, you can manually take a snapshot – just click on
Take snapshot now
.
44
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 ioSafe R4, so deactivating it when not needed may be advantageous in write-intensive environments.
When a snapshot is taken, snapshots of shares appear in your browse list alongside the original shares, except the snapshot share names have example, a snapshot taken of share
backup
–snap
appended to the original share names. For
will be available as
backup-snap
.
45
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 snapshot reserved 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 snapshot reserved space on the volume. If you look at the
Disk space
utilization information just below the
Volume
tab, you will see how much space has
been reserved for snapshots.
After 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 snapshot reserved space include new file creation, modifications, and deletions; for instance, any time you delete a 1MB file, the change caused by the deletion will use up 1MB of reserved space.
When the snapshot does become invalidated, an email alert will be sent and the status will be reflected in the Snapshot tab. The snapshot is no longer usable at this stage.
►
RESIZING SNAPSHOT SPACE
If you are constantly getting snapshot invalidation alerts, you may want to either increase the frequency of the snapshot, or consider increasing the snapshot reserved space. To do this, or to eliminate your existing snapshot space (thus increasing your usable volume space), you can specify the desired snapshot space in the Snapshot Space box. Simply select a value from the selection box
Save
and click
. Your snapshot space will be limited to approximately 100GB.
46
The process of resizing the snapshot space can take awhile depending on your data volume size and the number of files in your volume. Expanding the snapshot space will reduce your data volume size, and reducing the snapshot space will expand it.
Note
Due to the nature of how 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 last.
USB Storage
The USB tab displays the USB disk and flash devices connected to the ioSafe R4, and offers various options for these devices. A flash device will appear as USB_FLASH_1 and a disk device will appear as USB_HDD_1. If you have multiple devices, they will appear appended by an increasing device number, i.e. USB_HDD_2. If the device contains multiple partitions, the partitions will be listed beneath the main device entry.
47
Partitions on the storage devices must be one of the following file system formats:
 FAT32
 NTFS
 Ext2
 Ext3
To the right of the access icons are command options for the device. The following commands are available:
Disconnect
: This option prepares the USB partition for disconnection by properly
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 the file system is properly closed. The Disconnect option unmounts all partitions on the device. Once disconnected, physically remove and re-connect to the ioSafe R4 to regain access to the USB device.
Locate
: In cases where you attach multiple storage devices and wish to determine which
device corresponds to the device listing, the device LED, 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 ioSafe R4 devices. The advantage of EXT3 over FAT32 is that file ownership and mode information
Locate
command will blink the
48
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. The installation images can be downloaded from the web.
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 menu, and access restrictions can be specified there. The share names will reflect the USB device names.
USB Flash Device Option
Towards the lower portion of the USB Storage tab, you’ll notice the USB Flash Device Option. There, you can elect to copy the content of a USB flash device automatically on connect 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.
49
Shares
The Shares menu provides all the options pertaining to share services for the ioSafe R4 device. This entails share management (including data and print shares), volume management, and share service management.
We’ll first look at how we can control the services.
Adding Shares
To add a share, click on the
Volume
tab. If more than one volume is configured, click on the
volume you wish to add the share.
The
Add Share
tab has two looks, depending on the security mode. In the
Share
mode, you will enter the share name, description, and optional password and disk quota. The share password and share disk quota is available only in this security mode.
In the User or Domain security modes, the Add Share tab consists only of fields for the share name and description. Password and disk quotas are account-specific.
50
In either case, you can add up to five shares at a time. Once you finish adding the shares, you can refer to Chapter 2 for instructions on how to access them from different client interfaces.
Managing Shares
Once you have added shares, you may want to manually fine-tune share access in the tab. This tab has two looks, one for
Share
security mode and one for
User and Domain
Share List
mode. They’re both similar except for the password and disk quota prompts which only appear in Share mode.
51
If you want to delete a share, click on the checkbox to the far right of the share listing and click
Delete
. You have the option of deleting up to five shares at a time.
The columns to the left of the Delete checkbox represent the services that are currently enabled, and the access icons in those columns summarize the access rights to the share for each of the services. You can move the mouse pointer over the access icons to get a quick glimpse of the access settings.
The settings represent:
 Disabled
 Read-only Access
 Read/Write Access
 Read Access with exceptions
– Access to this share is disabled.
– Access to this share is read-only.
– Access to this share is read/write.
– Either (1) access to this share is read-only and only
allowed for specified hosts, (2) access is read-only except for one or more users or groups
52
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 only allowed 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 bring up the Share Options tab where you can set the access rules for each file protocol. Keep in mind that access options will differ between protocols.
►
SETTING SHARE ACCESS IN SHARE MODE
In Share mode, the CIFS/Windows share options tab will look as follows:
53
In this tab, you can select the default access at the top and optionally specify the host(s) that you wish to allow restrict access to in the Share Access Restriction box.
Share Access Restriction
For instance, select Access from all other hosts will be denied. For example, to allow only host
read-only
for default access and list the hosts you wish to allow access to.
192.168.2.101
read-only
access to the share, specify the following:
Default: Read-only Hosts allowed access: 192.168.2.101
Multiple hosts can be separated with commas (see
Appendix B
for more description of valid host formats.) For example, if you wish to limit access to the share to particular hosts, you can enter host IP addresses or valid DNS hostnames in the
Host allowed
access field. In addition, you can enter a
range of hosts using common IP range expressions such as:
192.168.2., 192.168.2.0/255.255.255.0, 192.168.2.0/24
The above designations all allow hosts with IP addresses
192.168.2.1
through
192.168.2.254.
Towards the bottom of the and
Opportunistic Locking

►
SETTING SHARE ACCESS IN USER AND DOMAIN MODES
In User or Domain modes, the same tab would look as follows (note the addition of read-only and write-enabled user and group fields):
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 ioSafe R4 or on the domain controller.
For instance, if you wish to allow read-only access to all and read/write access only user group
engr
, you would set the following:
Default: Read-only Write-enabled users: fred Write-enabled groups: engr
If you wish to limit the above access only to hosts
192.168.2.101
and
192.168.2.102
fred
and
, 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
Note that access control will differ slightly from service to service.
Share Display Option
Restricting access to a share will not prevent users from seeing the share in the browse list. In certain instances, this might not be desirable, such as for backup shares that you may want to prevent users from seeing. To hide a share, select the
Hide this share…
option. 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.
Recycle Bin
The ioSafe R4 can have a Recycle Bin for each share for Windows users. You will see the
Recycle Bin
option at the bottom of the
Windows [CIFS]
access tab.
Enable
When enabled, 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 where users can restore deleted files.
56
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 box offers options for setting the default permission of new files and folders created via CIFS. The default permission of newly created files is read/write for the owner and owner’s group and read-only for others (i.e. everyone). Permission for newly created folders is read/write for everyone. If the default doesn’t 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 remote file access through all file protocol interfaces. Care should be taken before using these options as anything that changes ownership and permissions may 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

58
USB Shares
USB storage devices are shared using the name of the device appended by the partition number. The base device name can be changed in the Volumes/USB tab if desired. The ioSafe R4 attempts to remember the name as long as there’s a unique ID associated with the USB device so that the next time the device is connected, the same share name(s) will be available. Share access restrictions are not saved across disconnects, however.
Note
Although access authorization is based on user login in non-Share mode, files saved on the USB device, regardless of the user account, are with UID
0. This is to allow easy sharing of the USB device with other ioSafe R4 and PC systems.
59
Printers
The ioSafe R4 device supports automatic recognition of USB printers. If you have not already done so, you can connect a printer now, wait a few seconds, and click
Refresh
to display detected printers. The print share name will automatically reflect the manufacturer and model of your printer and will list in the USB Printers tab.
Print Shares over CIFS/SMB
The ioSafe R4 can act as a print server for up to two USB printers for your Windows or Mac clients. For example, to setup a printer under Windows, click Browse in RAIDar or simply enter \\

60
Double-click the printer icon to assign a Windows driver.
IPP Printing
The ioSafe R4 also supports the IETF standard Internet Printing Protocol (IPP) over HTTP. Any client supporting IPP Printing (IPP is available natively on the latest Windows Versions and OS X) can now use this protocol to utilize printers connected to the ioSafe R4. The simplest way to utilize IPP Printing is to use
Bonjour
to discover and setup the print queue. Bonjour is built into OS X and can be installed on Windows (Bonjour for Windows is available for download from Apple’s website at http://www.apple.com/macosx/features/bonjour/ ).
Managing Print Queues
From time to time, printers may run out of ink, paper, or simply jam up, forcing you to deal with the print jobs stuck in a queue. The ioSafe R4 has a built-in print queue management to handle this. Simply go to the for any “stuck” printers.

Backup
The
Backup
manager integrated with the ioSafe R4 allows the ioSafe R4 to act as a backup appliance. Backup tasks can be controlled directly from the ioSafe R4 without the need for a client­based backup application.
With the flexibility to support full and incremental backups across FTP, HTTP, CIFS/SMB, and NFS protocols, the ioSafe R4 can act as a simple central repository for both home and office environments. And with multiple ioSafe R4 systems, you can set up one ioSafe R4 to backup another directly.
Adding a New Backup Job
To create a new backup job, click on the procedure on creating a job.
Add a New Backup Job
tab. You will notice a 4-step
62
►
STEP 1 – SELECT BACKUP SOURCE
The backup source can be located remotely or it can be a public, a private home share, or all home shares on the ioSafe R4.
A USB device will appear as a share, so if you want to backup a USB device, select on a share name starting with USB. If you want to backup data from a remote source, you will need to select from one of the following:
 Windows/NAS (Timestamp)
– select this if you wish to backup a share from a Windows PC or another ioSafe R4 device. Incremental backups use timestamps to determine whether files should be backed up.
63
 Windows/NAS (Archive Bit)
– select this if you wish to backup 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.
 Website
– select thi 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.
 FTP site
 NFS server
– select this if you wish to back up an FTP site or a path from that site.
– select this option if you wish to back up from a Linux/Unix server across NFS. Mac OS X users can also use this option by setting up a NFS share from the console terminal.
 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 ioSafe R4 systems.
Once you have selected a backup source, you can enter the path from that source. If you selected a ioSafe R4 share, you can either leave the path blank to backup the entire share, or enter a folder path. Note that you should use forward slashes, ‘/’, in place of backslashes (\).
If you selected a remote source, each remote protocol uses a slightly different notation for the path. If the path field is empty, selecting the remote source in the pull-down menu shows an example format of the path. Following are some examples:
Examples of a FTP path
ftp://myserver/mypath/mydir ftp://myserver/mypath/mydir/myfile
Examples of a Website path
http://www.mywebsite.com http://192.168.0.101/mypath/mydir
Examples of a Windows or remote NAS path
//myserver/myshare //myserver/myshare/myfolder //192.168.0.101/myshare/myfolder
Examples of NFS path
myserver:/mypath
192.168.0.101:/mypath/myfolder
Examples of Rsync path
myserver::mymodule/mypath
192.168.0.101::mymodule/mypath
Examples of local path
myfolder media/Videos My Folder My Documents/My Pictures
64
With a remote source, you may need to enter a login and password to access the share. If you are accessing a password-protected share on a remote ioSafe R4 server configured for Share security mode, enter the name of the share name for login.
You should click on the
Test Connection
button to make sure you have proper access to the
remote backup source before continuing.
►
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 had selected a remote backup source, you will need to select a public or a private home share on the ioSafe R4 (either the source or destination must be local to the ioSafe R4). If you selected an ioSafe R4 share for the source, you can either enter another local ioSafe R4 share for the destination, or you can specify a remote backup destination.
The remote backup destination can be a Windows PC/ioSafe R4 system, NFS server, or a Rsync server. Note that you can select Rsync for a remote ioSafe R4 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 four hours every day to 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 on those snapshots.
If you wish, you can elect not to schedule the backup job so that you can invoke it manually instead by not selecting the
Perform backup every…
check box. You may want to do this if you will be
starting the backup from the Backup Button on ioSafe R4 system.
►
STEP 4 – CHOOSE BACKUP OPTIONS
In this last step, select how you would like backups to be performed.
65
Schedule full backup
First, select when you want full backups to be performed. You can elect to do this just at the first time, every week, every two weeks, every three weeks, every four 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 Web or FTP site only have the option to do full backup every time.
Send 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 files are backed up as expected. You can elect to send only errors encountered during backup, full backup logs consisting of file listing (can be large), or status and errors (
Note
status
refers to completion status).
Backup log e-mails are restricted to approximately 10K lines. To view the full backup log (regardless of length), select Status > Logs and click the Download All Logs link.
Remove files from destination first
Select if you want to erase the destination path contents before the backup is performed. Be careful not to reverse your backup source and 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.
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. Do experiment with a test share to make sure you understand this option.
66
Change ownership of backup files
The Backup Manager attempts to maintain original file ownership whenever possible; however, this may 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.
Before trusting that your backup job to a schedule, it is always a good idea to manually perform the backup to make sure access to the remote backup source or destination is granted, and the backup job can be done within the backup frequency you selected. You can do this after clicking
Apply
to
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.
Here, you will see a summary of the backup jobs that have been scheduled. Jobs are numbered starting from 001. You can modify the backup job by clicking the Job number button.
If you wish, you can enable or disable the job scheduling by clicking on the
Enable
checkbox. Disabling the job will not delete the job, but rather take it out of the automatic scheduling. If you wish to delete the job, click the
Delete
button.
You can manually start the backup job by clicking Go. You will see the status change as the backup is started, encounters an error, or is finished.

68
System
To set up and manage your ioSafe R4 system effectively, review the settings in the following sections and make any necessary changes.
Clock
An accurate time setting on the Clock screen is required to ensure proper file timestamps. You can access the Clock screen by selecting System > Clock from the main menu.
►
SYSTEM TIME
The System Time tab in the Clock page allows you to set the date, time, and time zone. Set appropriately to ensure files maintain proper timestamp.
►
NTP OPTION
You can elect to synchronize the system time on the device with a remote NTP (Network Time Protocol) server. You can elect to keep the default servers or enter up to two NTP servers closer to your locale. Available public NTP servers can be found by searching the web.

to save your settings.
When you have saved the SNMP settings on the ioSafe R4, you can import the ioSafe SNMP MIB to your SNMP client application. The ioSafe MIB can be from the ioSafe Support site at http://www.iosafe.com.
72
►
SMTP
The ioSafe R4 system has a built-in email message transfer agent (MTA) that is set up to send alert email messages from the device. Some corporate environments, however, may have a firewall that blocks untrusted MTA’s from sending out messages.
If you were unable to receive the test message from the
Alerts Settings
tab, it may have been
blocked by the firewall. In that case, specify an appropriate SMTP server in this tab.
Internet Service Providers (ISP) for home may also block untrusted MTA’s. Furthermore, they may allow you to specify their SMTP server but require you to enter a user login and password to send out email – this is common with most DSL services. If this is the case, simply enter the user name and password in the fields provided.
73
Performance
If you wish to tweak the system performance, select the
Performance
tab in the
System
menu. Note that some of the settings suggest that you utilize an Uninterruptible Power Supply (UPS) before enabling that option.
Select
Disable full data journaling
to substantially improve disk write performance. During an unexpected power down without battery backup, there is a small chance that parity written to a disk in a RAID set may become out of sync with the data disks, possibly causing incorrect data to be recovered if one disk fails.
Disable journaling
Select
if you understand the consequences of this action, and you do not mind a long file system check (only after unexpected power failures). File system journaling allows disk checks of only a few seconds verses possibly an hour or longer without journaling. Disabling journaling will improve disk write performance slightly.
Note
You can buy a UPS with USB monitoring at a very reasonable cost. By safely allowing the performance options to be checked, you can effectively double your write performance and provide uninterrupted service of your ioSafe R4 for a very low price.
74
The
Optimize for OS X
option provides the best performance in Mac OS X environments when connected to the ioSafe R4 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 allows for fast write performance by enabling aggressive write-back caching over CIFS. Do not enable this option in multi-user application environments such as Quickbooks 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 FOR PERFORMANCE
Adding a UPS to the NAS is an easy way to protect against power failures, but as mentioned in the
System Performance
section, a UPS can also safely allow for a more aggressive performance setting. Simply connect the NAS power cable to the UPS and connect the UPS USB monitoring cable between the UPS and the NAS. The UPS will be detected automatically and will show up in the Status bar. You can move the mouse pointer over the UPS LED icon to display the current UPS information and battery life.
Note
Alert notification and automatic system optimization is available only with a UPS that utilizes a USB monitoring interface.
You are notified by email 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.
Make sure to adjust the optimization settings in the Performance tab if you wish to take advantage of the available options.
75
Language
The
Language
for file names.
tab offers the option of setting the ioSafe R4 device to the appropriate character set
For example, selecting Japanese allows sharing of files with Japanese names in Windows Explorer.
76
It is best to select the appropriate language based on the region that this device will operate in.
Note
This option does not set the web browser language display – browser settings must be done using the browser language option.
Unicode for User, Group, and Share Names
If desired, you can elect to enable use of Unicode for user, group, and share names, allowing for greater flexibility in non-English speaking regions. This option, once selected, cannot be reversed.
Note
HTTP and WebDAV access will not work with Unicode user names. Other restrictions may exist.
Enable Character encoding conversion for FTP clients
If your FTP client uses different character encoding from the NAS character encoding specified in Unicode, the NAS FTP server will convert to it if this option is selected.
Updating ioSafe R4
The ioSafe R4 device offers the option of upgrading the operating firmware either automatically using the Remote Update option or manually loading an update image downloaded from the ioSafe Support website.
►
REMOTE UPDATE
The preferred and quicker method if the ioSafe R4 has Internet access is the
Remote

To access this share from a Linux or Unix client, you will need to mount the share over NFS, i.e. type:
mount ipaddr:/backup /backup
where
backup
is the share name. Running the ls command in the mounted path displays the share
content.
Note
The ioSafe R4 does not support NIS as it is unable to correlate NIS information with CIFS logins. In mixed environments where CIFS and NFS integration is desired, you can set the security to User mode and manually specify the UID and GID of the user and group accounts to match your NIS or other Linux/Unix server settings. The ioSafe R4 provides the ability to import a comma-delimited file containing the user and group information to coordinate Linux/Unix login settings. Please see the Managing Users section for more information.

If the share access is read-only, the file manager will only display:
If the share is also writable, the file manager will have options for creating, modifying, and deleting files, as follows:
One useful application for a web share is for setting 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.
Note
Files created under the Web file manager can only be deleted under this file manager. The only exception is the admin user, who can change or delete any files created through the web.
Files not created from this file manager can be modified within the file manager but cannot be deleted here.
97
FTP / FTPS
To access the share via FTP in Share security mode, use “anonymous” as the login and your email address as the password.
Note
Enabling FTP access in Share mode opens up the share to anyone who has an FTP client on your network. It is best to enable FTP access only to shares you are comfortable making public on your network.
Warning
Disk usage using FTP in Share mode does not count towards the share disk quota, so carefully choose how you advertise a FTP Share.
To access the share in User or Domain security mode, use the appropriate user login and password used to access the ioSafe R4. For better security, you can use a FTPS (FTP-SSL) client to connect to the ioSafe R4 FTP service. With FTPS, password and data is encrypted.
98
Rsync
Access to the share via rsync is identical regardless of the security mode. If you had specified a user or password in the rsync share access tab, you will need to specify this when accessing the rsync share. Unlike other protocols, rsync uses arbitrary user name and password that is specific only for rsync access. The user account you specify does not need to exist on the ioSafe R4 or a domain controller.
Hers is an example of a way for a Linux client to list the content of an ioSafe R4 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
# rsync –a user@ipaddr::backup /tmp Passowrd: *****
