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.

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.

on page 107. 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.

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.
