Setting up rsync backup with Synology DiskStation (DSM 4.3)


A NAS is a storage medium with a network connection. This allow to store data centrally and make it available via network or the Internet at any time. For this purpose Synology provides a feature-rich and intuitive software.

This article assumes that you have done the following tasks for your DiskStation:

  • Hardware installation for Synology NAS.
  • Software installation for Synology DiskStation Manager (DSM, web-based operating system of Synology NAS).

  • If you are backing up files from a DiskStation to your own rsync-compatible server, you will need to enter the correct rsync backup account name and password. You will also need to choose the correct backup module with write privileges.

There are 2 backup modes for backup from Synology DiskStation to your rsync-compatible server:

  1. remote shell mode > mode will be enabled only when you enter an absolute path (starting with "/") in Backup module, and it only supports encrypted backup.
  2. rsync > is used when you select a backup module (shared folder on the rsync-compatible server) from the drop-down menu next to Backup module.
