+1 for Syncthing, I use it a lot. However anyone have any methods of 1-way sync? I’d like to backup camera photos from my phone with it but not have a 2-way sync so I can delete the pictures off my phone, and not have it deleted on my server. At one point I found a discussion with the developers about this exact use case and if I remember right, they were kind or in the camp of ‘that use case extends beyond what we envision for the app and would introduce more complexities, so we’re not a big fan of introducing that feature.’
