iSCSI LUN Snapshot/Backup
iSCSI LUN snapshot
Directly backing up an iSCSI LUN usually takes a long time. In addition, during backup a LUN usually continues to provide data access; this could cause backed up contents to be inconsistent with the original copy. QNAP provides LUN snapshot to overcome this. A snapshot uses little time to record the current LUN status, just like taking a picture. The IT administrator can further use the LUN snapshot to back up, restore, or allow access to the contents in the LUN.
LUN backup and restore
A LUN snapshot has the LUN status when the snapshot was taken. The IT administrator can use the LUN snapshot to back up contents in the LUN to various storage destinations, including Windows shared folders via SMB/CIFS, Linux shared folders via NFS, or simply local shared folders on the Turbo NAS. Instant and scheduled backup options are available.
In the event of LUN failure, the IT administrator can choose to restore the LUN by overwriting the original one or creating a new LUN.
LUN Snapshot access
Since a LUN snapshot has the LUN status in a certain time, when users need to obtain contents in that time, the IT administrator can mount the snapshot to an iSCSI target on the Turbo NAS to allow data access from users.
