Back up Data or iSCSI LUN on Synology NAS
Other than backing up computer data to Synology NAS, users belonging to the administrators group can back
up data or iSCSI LUN on the Synology NAS.
Ways to Back Up Synology NAS Data
Local Backup and Network Backup are ways you can choose to back up data or iSCSI LUN on your Synology
NAS. Plus, Synology NAS 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 NAS 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 NAS to another one 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 Synology NAS 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 NAS 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 Synology NAS data, go to Main Menu > Backup and Restore and click
the Help button (with a question mark) at the top-right corner.
