Microsoft Volume Shadow Copy Service
Microsoft includes Volume Shadow Copy Service (VSS) in Windows 2003 and Windows 2008
to simplify the enterprise’s storage environment, which provides a framework for creating a
point-in-time copy of either a single volume or multiple volumes.
Microsoft Windows Server 2008 VSS works with VSS-aware applications that are used to determine
when a volume shadow copy (snapshot) can be made. (A snapshot is a virtual copy: a copy of
some data set—for example, a disk volume—at a point in time.) Before making a snapshot, VSS
communicates with the operating system and applications to freeze computing tasks, which enables
an application-consistent snapshot to be taken. The shadow copy volume is then used for the actual
backup. After VSS saves the shadow copy volume on the backup device, it deletes the shadow
copy.
