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.
In this chapter, the following topics are covered:
Backing up iSCSI LUNs
Restoring iSCSI LUNs
Creating iSCSI LUN Snapshots
Managing LUN Backup/Restore/Snapshot by Command Line
B a c king up iSC SI 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, follow these steps.
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
automatically create a point-in-time snapshot for the LUN.
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". (More system resources will be used for compression, but
the backup LUN size 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 will be shown on the list.
