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.
Note: The function or its content is only applicable to some models. To check for
applicable models, please refer to the product comparison table on the QNAP website.
Backing up LUNs
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 that at least one iSCSI LUN has been created
on the NAS. To create an iSCSI target and LUN, follow the steps below:
1. Go to “Storage Manager” > “LUN Backup”. Click “Create a job”.
2. Select “Back up an iSCSI LUN” and click “Next”.
