ReadyNAS OS 6.1 Recover Data from a Snapshot to an iSCSI-Attached Device Strictly speaking, users who access the ReadyNAS 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 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 139. 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 104. 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 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. Snapshots 149
