LUN Backup
Under the Backup tab of Back and Restore, you can use Local LUN Backup to back up the iSCSI LUNs of your RackStation to local shared folders. You can also use Network LUN Backup to back up to another RackStation.
Note:
-
Before performing Network LUN Backup, please log in to the destination RackStation to make sure its Network Backup Service is enabled in Synology Backup Mode (at Main Menu > Control Panel > Network Backup > Network Backup).
-
If your RackStation 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:
-
Choose Create > LUN backup task to open the LUN Backup Wizard, and click Next.
-
When you are prompted to choose a destination type, choose either of the following:
-
Local LUN Backup: Choose this option to back up the LUN from RackStation to a local shared folder or an external disk that is connected to the USB or eSATA port of your RackStation.
- Network LUN Backup: Choose this option to back up LUN from your RackStation to another RackStation.
-
When prompted, specify the backup destination and source LUN, and set the backup schedule.
-
Follow the wizard to complete the setup.
After the backup task is created, RackStation 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:
-
File-based and block-based LUNs are both available for backup.
-
Each backup task can only include one LUN as backup source.
-
Backing up iSCSI LUNs to an external disk with the FAT or NTFS format is not supported.
About Full Backup and Incremental Backup:
RackStation 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, RackStation will perform a full backup for the task again.
