LUN Backup

Under the Backup tab of Back and Restore, you can use Local LUN Backup to back up the iSCSI LUNs of your DiskStation to local shared folders. You can also use Network LUN Backup to back up to another DiskStation.

    Note:
  1. Before performing Network LUN Backup, please log in to the destination DiskStation to make sure its Network Backup Service is enabled in Synology Backup Mode (at Main Menu > Control Panel > Network Backup > Network Backup).
  2. If your DiskStation connects to the network through a router, make sure you have specified a port forwarding rule for the iSCSI service (TCP port 3260) on the router before performing Network LUN Backup.

To back up an iSCSI LUN:

  1. Choose Create > LUN backup task to open the LUN Backup Wizard, and click Next.
  2. When you are prompted to choose a destination type, choose either of the following:
  3. When prompted, specify the backup destination and source LUN, and set the backup schedule.
  4. Follow the wizard to complete the setup.

After the backup task is created, DiskStation will perform the backup task on schedule and store the backup LUN at the destination. The backup LUN is used for backup purpose only. To access the backup LUN, see To restore the backup LUN below for more information.

    Note:
  1. File-based and block-based LUNs are both available for backup.
  2. Each backup task can only include one LUN as backup source.
  3. Backing up iSCSI LUNs to an external disk with the FAT or NTFS format is not supported.

About Full Backup and Incremental Backup:

DiskStation will perform a full backup of the selected LUN for the first time, and then perform incremental backup afterwards. However, if the shared folder name or directory name of the backup destination is changed, DiskStation will perform a full backup for the task again.
