Creating a restore point for machines running Windows has be a feature since Windows ME. It has been developed with the advent of Windows 2000 and XP. Basically it creates a "snapshot" of the system and then uses that image to roll back to in case anything should go wrong. Fine in theory, but something rarely used in practice.
That aside, having a restore point is something of some worth and this product takes the concept a lot further. Recovery Manager is a networked version of the same thing but with a few more bells and whistles attached.
