You can set it to sync only on wifi and/or only when charging, which has always done the job for me. Depends on your use case, but things like password DBs need

You can set it to sync only on wifi and/or only when charging, which has always done the job for me. Depends on your use case, but things like password DBs need to be update-able from both directions, which rsync doesn't really do. On the other hand, I can rely on the fact that I don't need my home to be sync'd up unless I'm actually at home, on wifi.
