Back up Data or iSCSI LUN on Synology DiskStation
Other than backing up computer data to Synology DiskStation, users belonging to the administrators group can
back up data or iSCSI LUN on the DiskStation.
Ways to Back Up Synology DiskStation Data
Local Backup and Network Backup are ways you can choose to back up data or iSCSI LUN on your
Synology DiskStation. Plus, Synology DiskStation also supports Amazon S3 Backup, allowing you to back up
data to the Amazon S3 Server. Go to Main Menu > Backup and Restore > Create to take advantage of the
below backup methods. For more detailed instructions, please see DSM Help.
Local Backup
Local Backup allows backing up data from the Synology DiskStation to a system shared folder or an external disk
via USB or eSATA interface. The backups will be saved in a sub-folder named "LocalBackup" under the
destination shared folder.
Note: You may need to format the external disk before performing Local Backup to the disk for the first time.
Network Backup
Network Backup allows backing up data from the Synology DiskStation to another Synology server or an rsync-
compatible server. There are two modes available for Network Backup: non-encrypted and encrypted.
Encrypted mode provides better security, while non-encrypted mode provides better performance. To ensure
backup efficiency, it is recommended that you choose encrypted backup for important files.
Note: For more information about enabling Network Backup Service to set up your DiskStation as a backup
destination, go to Main Menu > Control Panel > Network Backup, and click the Help button (with a question mark)
at the top-right corner.
Amazon S3 Backup
Amazon S3 Backup allows backing up data from the Synology DiskStation to an Amazon S3 server. After you
perform an Amazon S3 Backup task, a single backup file will be stored in a Bucket on Amazon S3 Server, which
is identified by a unique Set KEY Value that begins with SourceServerName_MAC address, and ends with the
complete file path of this file.
With Amazon S3 Backup, backing up to Amazon S3 RRS (Reduced Redundancy Storage) is also supported.
Note:
 There are also encrypted and non-encrypted modes for Amazon S3 Backup.
 Fees may apply to use the Amazon S3 Backup service.
 For more information about backing up DiskStation data, go to Main Menu > Backup and Restore and click the
Help button (with a question mark) at the top-right corner.
