It uses "snapshot"-style backups with hard links to create the illusion of multiple, full backups without much of the space or processing overhead.
Scripts and configuration examples are given for
- Linux clients
- Windows clients (using cygwin)
- Synology server
On synology server,
- create a regular user named backup, and allow access to rsync
