Setting up rsync backup with Synology DiskStation (DSM 5.0)


Setting up rsync backup with Synology DiskStation (DSM 5.0)


A NAS is a storage medium with a network connection, data can be stored centrally and are Network & Internet available at all times. For this purpose Synology provides a feature-rich and intuitive software.

Before You Start

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).


  • Under Linux only the accounts "admin", "root" and "rsync" are allowed to perform backup tasks.
  • If you are backing up files from a DiskStation to your own rsync-compatible server, you will need to input the correct rsync backup account name and password. You will also need to choose the correct backup module with Write privilege.

There are 2 backup modes for backing up 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.

Creating volumes and shared folders

To create a shared folder, proceed as follows:

  • Log in to DSM 5.0 with your user credentials.
  • Go to Main Menu > Control Panel > Shared Folder.


Assign folder name

  • Select Create and under name enter the name of the folder. Then Click OK.


Assign Read/Write privilege

  • Under Permissions assign the Read/Write privilege to the users. Then Click OK.


Back up data from Synology NAS to another server

To Back up Synology NAS server data to another server, proceed as follows:

  • Go to Main Menu > Backup and Replication.


  • Select Backup > Create > Data backup task.


Select source and destination

  • Under Source and destination select the shared folder to backup.
  • Under Backup Destination > arrow down select Add Backup Destination.


Note: If you already have set a Backup Destination, proceed as follows:
