from a Network-Attached Device on page 89.
3. Locate the snapshot data on the ReadyNAS.
Snapshot data is stored in a snapshot subfolder within the share. Users with read/write
access to the shared folder can explore the snapshot data and recover earlier versions
of files or folders.
Recover Data From a Snapshot to an iSCSI-Attached Device
Strictly speaking, users who access the ReadyNAS through an iSCSI-attached device
cannot access snapshots. However, you can clone a snapshot of a LUN to become a
new independent LUN, and then assign the LUN clone to a LUN group that the users
can access.
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.
Recovering data from a snapshot to an iSCSI-attached device involves the following
high-level steps:
1. Clone a snapshot of a LUN.
See Clone Snapshots on page 131. Cloning a snapshot of a LUN creates a new
independent LUN.
2. Assign the LUN clone to a LUN group that the users can access.
See Assign a LUN to a LUN Group on page 105.
The LUN clone appears on the iSCSI-attached device as a virtual block device. The
iSCSI-attached device treats LUNs in the LUN group as locally attached disks. Now
users can access the LUN clone from the iSCSI-attached device.
3. Locate the snapshot data on the LUN clone from the iSCSI-attached device.
Users can access data on the LUN clone according to their access rights. Users with
read/write access to the LUNs in the LUN group can explore the snapshot data in
the LUN clone and recover any desired data.
