Probably overkill. It should work fine for text data, however, I don't
think it would scale well for binary data. I'm not sure it would handle
things like a changed exif comment gracefully. In my experience git
becomes sluggish for large repositories of GBs worth of data and I have
hundreds of GB of data.

I use a custom rsync-script that keeps hard links of all unchanged
files. Occasionally, I delete old backups and I think it's not
straightforward to achieve that with git.
