Reflect backs up your entire disk to an image file. You don't need to worry about anything to do with system state (such as the registry)

Well, I can think of some reasons why I would want to - let me give you an example. Let's say I have a machine that I use regularly and update data in it frequently, and then at the end of the day I back it up. If I have a registry/system state problem, then I would have to restore a whole partition. That would mean that I would have to find all of the files that had changed during the day, copy them somewhere, restore the whole partition from backup, then copy my data back. Active Directory backups are included in the system state, so that would be another reason to be able to restore that without the rest of the data files, etc.
