Think of the snapshot functionality this way. You're running some application, and a new version comes out. You're thinking about upgrading, but you don't want to mess up your production environment. If you take a snapshot before you start the upgrade process, you essentially have a point that you can rollback to, in case the upgrade goes badly. Once (and if) the upgrade goes smoothly, you can delete the snapshot, and the delta is merged into the existing image, and you lose the ability to rollback, but you get your full speed back. Make sense?
