Netgear RN31664E – ReadyNAS 316 6-Bay, 6x4TB Enterprise Drive Guía Del Software

Snapshot data is stored in a snapshot subfolder within the shared folder. Users with read/write access
to the shared folder can explore the snapshot data and recover earlier versions of files or folders.

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:

Clone a snapshot of a LUN.
See 

 on page 107. Cloning a snapshot of a LUN creates a new independent LUN.

Assign the LUN clone to a LUN group that the users can access.
See 

 on page 84.

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.

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.
