I use Syncthing for this type of task on my PC and Phone and it stores a copy of the shared folder on the server with the option for file versioning. Having a Server is optional by the way.

I concur. Bottles just works for me. I hat to tinker a bit to get Avatar working, but it just works and with no performance problems apart from my Desktop Environment crashing after 4 hours of playing. But I think that's a different problem. :/

My main server is called Master and my server for testing is called lenno because it's an old Lenovo PC. Ich habe two zfs pools on my main server called Avalon and the newest one is called Pegasus. I named them after the two galaxies from the Star Gate TV Shows.
