4.2.5.4 LUN Backup

The NAS supports backing up iSCSI LUNs to different storage locations (Windows, Linux,

or local shared folders), restoring the LUNs to the NAS, or creating a LUN snapshot and

mapping it to an iSCSI target.

Backing up iSCSI LUNs

Before backing up an iSCSI LUN, make sure at least one iSCSI LUN has been created on

the NAS. To create iSCSI targets and LUN, go to "Storage Manager" > "iSCSI" > "Target

Management".

1. Go to "Storage Manager" > "iSCSI" > "LUN Backup". Click "Create a new job".

2. Select "Back up an iSCSI LUN" and click "Next".

3. Select the source LUN for backup. If an online LUN is selected, the NAS will create a

point-in-time snapshot for the LUN automatically.

4. Specify the destination where the LUN will be backed up to. The NAS supports LUN

backup to a Linux share (NFS), a Windows share (CIFS/SMB), and a local folder on

the NAS. Click "Test" to test the connection to the specified path. Then click "Next".

5. Enter a name of the backup LUN image or use the one generated by the NAS. Select

the subfolder where the image file will be stored. Select to use compression or not

and click "Next". (Use Compression: When this option is enabled, more CPU resources

of the NAS will be consumed but the size of the backup LUN can be reduced. The

backup time may vary depending on the size of the iSCSI LUN.)

6. Specify the backup schedule, choose the backup period (Now, Hourly, Daily, Weekly,

or Monthly) and click "Next".

7. The settings will be shown. Enter a name for the job or use the one generated by the

NAS. Click "Next."

8. Click "Finish" to exit.

9. The backup job is shown on the list.
