General

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.

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.
