I've had the luxury of 50GB free Dropbox space courtesy of an offer that came with my Android tablet, but that is now about to expire. I've been wanting to shift to something else anyway so now's the time.
But what do I pick? There are several options...
Objective: To be able to sync as much stuff as I like. I have no desire for a central repository (although I could set one up if needed); I prefer a peer to peer model. I'd really prefer a good sync mechanism (in particularly handling file deltas rather than having to upload a whole file if something changes). ARM compatibility is important. Android integration would be a big plus (eg I like that my phone automatically uploads photos to Dropbox, I'd like to move them to the new solution).
BTSync: Free only as in beer but otherwise looks pretty good. Syncthing (now called Pulse): Properly free. I think it meets all my criteria.
Any others I should consider? Any experiences to report?
