Reading that site, it sounds EXACTLY like snapshots. It doesn't sound to require a second disk, it just gives you the option of backing up to one. Sounds like it snapshots once a day (configurable) and then "sends" the snapshot to another drive/server if you request it to do so. Looks like they just made snapshots accesible to desktop users. Pretty impressive how they did the GUI work too.
