Yep, I use Apple Time Machine for much the same purpose. Once you've set it up, it's always on, you can just go back in time (the granularity is once per hour, but that's been enough every time I've needed to use it) and restore (or make a copy of) any file or folder. Saved me quite a few times when Git has let me down.
