There's a lot of services out there to sync your phone data with the cloud, but what if you'd rather backup your own data to your own server at home? Unfortunately the play store didn't provide anything I would deem useful enough to actually use it. Admittedly there's a bunch of useful sync apps out there but they usually backup your photos or videos or music, but not all of it. The only thing that looks really interesting is BitTorrent Sync, so if you're searching for an app that's probably the best you can get at the moment. If you're still reading you're probably interested in something else. So your android device is running Linux, right? So why not use ssh and rsync to connect to your phone and backup your data!
