4.2.3.3 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.
Ba cking up iSC SI LU Ns
The entire LUN can be backed up as an image file and saved to a different location. The
storage location can be a Windows share (SMB/CIFS), a Linux share (NFS), or a local
folder on the NAS.
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" > "LUN Backup".
1. 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.
Refer to the table below for actions (the "Action" button on the figure above) available
to manage the backup jobs.
