About Managing Snapshots with Hyper-V

Hyper-V introduces the concept of virtual machine snapshots – which is to say point in time images of a virtual machine that you can return to at any stage.  These snapshots are implemented in the virtualization layer – and can be taken at any time with any guest operating system (even during an operating system installation).  Snapshots can be taken whether the virtual machine is running or stopped.  If the virtual machine is running when the snapshot is taken there is no downtime involved to create the snapshot.
