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 then 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.
In order 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.
To recover data from a snapshot to an iSCSI-attached device:
1. Clone a snapshot of a LUN.
Cloning a snapshot of a LUN creates a new independent LUN. For more information on cloning a snapshot, see the How do I clone a snapshot using the snapshot timeline on my ReadyDATA storage system?
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. For more information, see theHow do I create a LUN group and assign LUNs to LUN groups on my ReadyDATA storage system?
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 who have read/write access to the LUNs in the LUN group can explore the snapshot data in the LUN clone and recover any desired data.
