Users who do not back up their data can still be protected from data loss if you provide them
access to data that is available in a snapshot on the ReadyDATA. Access to snapshots
differs according to the type of attached device that a user employs.

Recover Data from a Snapshot to a Network-Attached Device
For snapshots to be accessible to users from their network-attached device, you must select
the Allow snapshot access check box in the Protection section of the Properties pane of a
share. For more information, see

After you make snapshots available, users with a network-attached device have access to
the snapshots that reside on a share on the ReadyDATA according to their access rights.
For those users with read/write access to the share, recovering data is a simple process:
They click the snapshot subfolder in a share, and then have access to all snapshots that are
available on that share. Users can explore the data that is available in a snapshot and
recover any desired file or folder.

Recover Data from a Snapshot to an iSCSI-Attached Device
Strictly speaking, users who access the ReadyDATA through an iSCSI-attached device do
not have access to snapshots. However, you can clone a snapshot of a LUN to become a
new independent LUN and assign that LUN clone to a LUN group that the users can access.

Cloning a snapshot to become a LUN is an instantaneous process that does not consume
additional storage space, unless more data is written to the clone. Because no additional
storage space is consumed, cloning snapshots is very efficient.

To recover data from the LUN clone, users must access the LUN clone from the same type of
iSCSI-attached device that was used to format the parent of the clone. For example, if the
parent LUN was formatted using a Windows device, users must access the LUN clone using
a Windows device.
