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.
Local Backup
Local Backup allows you to back up data to the LocalBackup folder in the following locations on your
Synology DiskStation:
 Another shared folder
 An external USB or eSATA Disk attached to your Synology DiskStation
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 you to back up data to the NetBackup folder in the following locations within the Intranet
or over the Internet:
 Another Synology DiskStation
 A rsync-compatible server
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 Simple Storage Service (S3) Backup allows you to back up data to the 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.
