From the drop-down menu, select server or IPv4 Use values from a DHCP 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 o 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 to locate the device, and then reconnect.Rescan
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 drop-down menu, select server or IPv6 Use values from a DHCP Use values
below:
• Congure Automatically
In most networks where a DHCP server is enabled, you can specify the Congure
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 o 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

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 x 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 benet of combining two or more Ethernet interfaces is that failover is supported.
With failover, if one Ethernet interface fails, trac is automatically directed to the other
Ethernet interfaces.

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 - followed by the last 3 bytes of its primary MAC address.nas
Default Gateway
The default gateway species the IP address of the system where your network trac is
routed if the destination is outside your subnet. In most homes and smaller oces, 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 eld is
automatically populated with the setting from your DHCP server. If you selected the static
option, you can manually specify the IP address of the default gateway server here.
DNS Settings
The DNS area allows you to specify up to three domain name service servers for hostname
resolution. The DNS service translates host names into IP addresses.
If you selected the DHCP option in the Ethernet screen, the elds are Domain Name Server
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.
Managing Your ReadyNAS System

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 Conguration Protocol) service simplies 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 check box to make the ReadyNAS device act as a DHCP Enable DHCP service
server. This is convenient in networks where DHCP service is not already available.
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 conicts. If you want to
use this device as a DHCP server, make sure to specify static
addresses in the Ethernet and DNS tabs.

As a safeguard, you are requested to enter a password recovery question, the expected
answer, and an email address. If, in the future, you forget the password, go to
https://<readynas ip_address>/password_recovery. Successfully answering the
questions resets the admin password, which is then sent to the email address you enter on
this screen.
Password Recovery
To recover a forgotten password:
There are two options for recovering or resetting a lost or compromised password:
1. In a Web browser, enter https://<readynas ip_address>/password_recovery. You will
be prompted for the email address and security question entered when you rst set up
the system. A new password will be sent to you at that email.
2. Optionally, you can reinstall the firmware, which does not remove data from the system, but
resets the admin username and password to the factory defaults admin and netgear1.

3. Enter a hostname or an IP address in the Trap destination field. This is where all trap
messages will be sent. The following system events generate a trap:
• Abnormal power voltage
• Abnormal board enclosure temperature
• Fan failure
• UPS connected
• UPS detected power failure
• RAID disk sync started and nished
• RAID disk added, removed, and failure
• Snapshot invalidated
4. If you want to limit SNMP access to only a secure list of hosts, specify the hosts in the
Hosts allowed access field.

Understanding Volume Management
The ReadyNAS family oers 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 congure it
to use added disks to expand storage space or to increase data protection.
To expand storage space when adding drives, in the section, select the Next added drive
Will be used to expand volume radio button. To increase data protection when adding
drives, select the radio button.Will be used to add dual redundancy
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 rst 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 Your ReadyNAS System
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 o the unit.
Simply replace the rst 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 exible 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
congure 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.

ReadyNAS for Business RAIDiator 4.2.17
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
space.
• Hot spare disk is supported.
• Volume expansion without data loss is supported.
• Full volume management is available. You can create RAID level 0, 1, 5, or 6
volumes, specify the volume size, delete a disk from a volume, assign a hot spare,
and so on.
• Multiple volumes are supported, each with a different RAID level, snapshot schedule,
and disk quota denition.
• Each disk can be replaced, one by one, then rebuilt; after the last disk is replaced,
another data volume using the newly added capacity can be congured.
Volume Expansion
You can expand volumes in Flex-RAID mode without losing data.
To expand Flex-RAID volumes:
1. Select Volume > Volume Settings.
The Volume Settings screen displays.
2. In the Available Disks pane, select the Add To Volume check box for the disk where you
want to expand the volume.
A pop-up window displays advising you that the disk will be used for volume expansion
after you reboot your unit.
3. Click the OK button.
The pop-up window closes.
4. Click the Apply button.

Changing between X-RAID2 and Flex-RAID Modes
RAID 0, 1, and 5 are part of the Flex-RAID RAID levels. To switch from Flex-RAID mode to
X-RAID2 (expandable RAID), you need to backup your data rst, and then reset your
ReadyNAS back to factory default.
During the factory default process, you have a 10-minute window during the boot process to
click the button in RAIDarSetup , and set the box to the desired RAID mode (Flex-RAID or
X-RAID2). The RAIDar utility sends a prompt to during this 10-minute time Click Setup

Setting Security Access Modes
The ReadyNAS oers the and security access options. User Domain
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 oce 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. The
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.
Manage User Accounts
55
ReadyNAS for Business RAIDiator 4.2.17
User Security Mode
This mode is ideal for small and medium-size oces 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 species 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, and by the administrator to perform
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:
• Workgroup name
• Group names you want to create (for example, Marketing, Sales, Engineering)
• User names you want to create (plus email addresses if you will be setting disk
quotas)
• Amount of disk space you want to allocate to users and groups (optional)
To change or set a workgroup name:
1. UserSelect the radio button.
2. Enter the name you want to use in the Workgroup field in the User section. The name can
be the workgroup name that is already used on your Windows network.
3. Click Apply to save your changes.
Manage User Accounts
59
ReadyNAS for Business RAIDiator 4.2.17
Managing Users
To manage user accounts:
1. Select Manage Users from the pull-down menu.
2. Click the Add User screen to add a new user. You can add up to five users at a time.
For each user, add the following information:
• User name
• Email address
• User ID
• Group association from the Primary Group pull-down menu
• Password
• Disk quota
3. Click Apply to save your settings.
Only the Username and Password elds are
required; however, you should specify a 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 specied disk quota
limit.
If you do not want to assign a disk quota, enter 0.
If you want to add a large number of users, select
Import user list from the pull-down menu and
browse to locate the le containing the group list.
Manage User Accounts
62
ReadyNAS for Business RAIDiator 4.2.17
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 ner-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 eld 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 to All
list all groups.
To add a large number of groups, select from the pull-down menu, and Import group list
browse to locate the le containing the group list. You can upload a CSV (comma-separated
values) formatted le containing the group account information.
The le format is:
name1,gid1,quota1,member11:member12:member13
name2,gid2,quota2,member21:member22:member23
name3,gid3,quota3,member31:member32:member33
:
Note the following:
• Spaces around commas are ignored.
• The name eld is required.
• Quota is set to the default if not specied.
• GID is automatically generated if not specied.
• Empty elds 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 elds if you want to accept the system defaults for those elds, or you can leave the
elds empty:
intstones
In this example, the group is created with an automatically assigned GID and intstones
default quota.

Changing User Passwords
In User security mode there are two ways user passwords can be changed.
1. The preferred method is to allow users to change their own passwords.
a. Open a Web browser and use your existing password to log in to access the Web
share listing screen at . https://<ip_addr>/
b. PasswordSelect the screen, and follow the prompts to set a new password.
This encourages users to change their passwords on a more regular basis for
enhanced security, and relieves the administrator from this task.
2. Optionally, the administrator can change the passwords.
a. Security > User & Group Select Accounts.
b. Select Manage Users from the pull-down menu.
c. Select the user whose password needs to be reset.
d. Enter a new password in the Password eld.
e. Click Apply to save changes.
Note: In Domain security mode, the Password screen does not appear.
User passwords in Domain mode must be set on the domain or ADS
server.
Manage & Access Shares
68
ReadyNAS for Business RAIDiator 4.2.17
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 nancial information, only the nance group and specied
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 > Add Shares.
If more than one volume is congured, click the volume where you want to add the share.
2. Enter the share name and description.
Once you nish adding the shares, they will be accessible from dierent client operating
systems, as described later in this chapter.
Note: Enabling public access means anyone on the network without a
user account on the ReadyNAS can access the share.

Advanced CIFS Permission
The Advanced CIFS Permission section offers options for setting the default permission of
new les and folders created through CIFS. The default permission for newly created les 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
les residing on the ReadyNAS to be cached locally on the Windows client with the le or les
opened, thus eliminating network latency when the les are constantly accessed.
When another client attempts to open the same le or les, the cached data is written to the
ReadyNAS, and the oplock is released.

b. Authentication mode.
• Anonymous: No login information is required for FTP users.
• User: Users need an account congured on the ReadyNAS from either User or
Domain security mode.
c. Allow upload resumes. This option allows users to nish uploading a le to the FTP
share if the connection had been previously interrupted. Without this option enabled,
if the connection is dropped at 50 percent completion, the le upload must restart
from the beginning.
d. Passive ports. This port range is required to enable remote access to the
ReadyNAS from over the Internet. This port range should be adjusted to the
maximum number of concurrent sessions you expect to run at one time. If you
expect frequent concurrent access from many users, double this number, as each
FTP user will consume a passive port.
e. Masquerade as. This eld adjusts the hostname that the FTP server reports to an
FTP client.

see on page 103.Enabling Rsync and Specifying Rsync Rights
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 le
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 to add the public keyManage SSH Keys .
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 les 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 les and directories that you want
to exclude from the backup. Enter the les and directories as a comma-separated
list.
• iSCSI. Backs up from an iSCSI source.
3. Select a backup destination.

• 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 rst 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 rst 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.

94
ReadyNAS for Business RAIDiator 4.2.17
• 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
les are backed up as expected. You can elect to send only errors encountered
during backup, full backup logs consisting of le listings (can be large), or status and
errors (status refers to completion status).
Note: Backup log emails are restricted to approximately 10K lines. To view
the full backup log (regardless of length), select and Status > Logs
click the Download All Logs link.
• Remove les 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 les 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 les. The Backup Manager attempts to maintain
original le ownership whenever possible; however, this might cause problems in
Share Security mode when backup les are accessed. To work around this, you have
the option of automatically changing the ownership of the backed-up les to match the
ownership of the share. This allows anyone who can access the backup share to
have full access to the backed-up les.
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.

Snapshots
The Volume 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, oine backups tend to become increasingly difcult because
backup time increases beyond oine hours. Snapshots allow backups to occur without the
need to take your systems oine.
Snapshots can also be used as temporary backups. For example, if a le on the ReadyNAS
device becomes infected with a virus, the uninfected le can be restored from a prior
snapshot taken before the attack.
Taking and Scheduling Snapshots
To take or schedule a snapshot:
1. From the Volume Snapshot screen, click the screen to display the Snapshot screen.
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 Volume screen, you did
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 11 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 Take snapshot now button.
Take snapshot

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 aect 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 is available as .music music-snap
You 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 eld.
Snapshots can expire when the reserved snapshot space is lled. 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 utilization eld on the Disk space 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 le creation, modications, and deletions; for instance, any time
you delete a 1MB le, 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 reected
on the Snapshot screen. The snapshot is no longer usable at this stage.

Enabling Rsync and Specifying Rsync Rights
Rsync is a fast and extraordinarily versatile le copying tool. It is famous for its delta-transfer
algorithm. This tool reduces the amount of data sent over the network by sending only the
dierences between the source les and the existing les in the destination. Rsync is widely
used for backups and mirroring.
Unlike other protocols, Rsync uses an arbitrary user name and password that are used only
for Rsync access. To encrypt Rsync data transfers, run Rsync over SSH. Access to the share
through Rsync is identical regardless of the security mode. The user account you specify
does not need to exist on the ReadyNAS, or a domain controller.
You will see Rsync setting icons on the Share Listing screen if the Rsync service is enabled
on the ReadyNAS.
To enable the Rsync service:
1. Select .Services > Standard File Protocols
2. Select the default access rights.
3. Assign a user name and password.
You need to specify this when doing an Rsync backup.
See 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 ecient use of incremental le transfers. This is the preferred backup
method between two ReadyNAS devices. For more information, see Enabling Rsync and
Specifying Rsync Rights on page 103. on page 90.
To enable Rsync access to a share or change access restrictions:
1. Click the Rsync icon on the Share Listing screen.

Understanding RAID
RAID is a well-established technology, and stands for Redundant Array of Independent
Disks, which is a way of protecting your data in case of a disk failure. High-quality reference
material about RAID is widely available on the Internet at sites like Wikipedia
( ), which is the source of the following information.http://en.wikipedia.org/wiki/RAID
RAID is used as an umbrella term for computer data storage schemes that can combine and
replicate data among multiple hard disk drives. The different schemes and architectures are
named by the word RAID followed by a number, as in RAID 0, RAID 1, and so on. RAID is
designed to meet one of two key goals: increased data reliability or increased I/O
performance. When multiple physical disks are set to use RAID technology, they are said to
be in a RAID array. This array distributes data across multiple disks, but the array is seen by
the operating system and computer user as one single disk.
RAID Basics
RAID redundancy is achieved by either writing the same data to multiple drives (known as
mirroring), or writing extra data (known as parity data) across the array, calculated such that
the failure of one (or more, depending on the type of RAID) disks in the array will not result in
loss of data. A failed disk can be replaced by a new one, and the lost data can be
reconstructed from the remaining data and the parity data.
Organizing disks into a redundant array decreases the usable storage capacity.
For instance,
• a 2-disk RAID 1 array loses half of the total capacity that would have otherwise been
available using both disks independently.
• a RAID 5 array with several disks loses the capacity of one disk. Other types of RAID
arrays are arranged so they are faster to write to, and read from, than a single disk.
RAID Levels
There are various RAID combinations that give various levels of protection against data loss,
capacity, and speed. RAID levels 0, 1, and 5 are the most commonly found, and cover most
requirements.
• RAID 0 (striped disks) distributes data across several disks in a way that gives
improved speed and no lost capacity, but all data on all disks will be lost if any one
disk fails. Although such an array has no actual redundancy, it is customary to call it
RAID 0.
• RAID 1 (mirrored settings/disks) duplicates data across every disk in the array,
providing full redundancy. Two (or more) disks each store exactly the same data, at
the same time, and at all times. Data is not lost as long as one disk survives. Total
capacity of the array equals the capacity of the smallest disk in the array. At any given
instant, the contents of each disk in the array are identical to those of every other disk
in the array.
