After the success with getting TimeMachine to back up to our NAS server I was eager to see if the NAS server could be used for something else, say a Subversion server for instance.
Turns out I was not the only one with that idea. It was even described on Synologys own wiki. Therefore, all you need to do to get Subversion running on your DS207+ is follow the simple steps described on Synologys wiki. Have fun!
