Rolling back or cloning the snapshot lets you get back deleted files, or reverting a bad update or config change... The snapshot is also a point in time to derive backups from, and usually costs nothing to make, as opposed to making a dd image of the disk, or tarballing everything, etc. Whether you think you need those is debatable, but it's quick and easy enough, works for me.
