Microsoft Volume Shadow Copy Service

Microsoft includes VSS (Volume Shadow Copy Service) in Windows to simplify the enterprise’s
storage environment. It provides a framework for creating a point-in-time copy of either a single
volume or multiple volumes.

Microsoft Windows Server VSS works with the VSS-aware applications that are in use 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.) VSS then communicates with the
operating system and applications and freezes I/O to thestorage system to allow snapshot creation
(without the freeze function, data could become corrupted when the snapshot is taken because the
system might be in the middle of a task). Meanwhile, applications continue to run uninterrupted.
The original volume continues to change as the process continues, but the shadow copy of the
volume remains constant. VSS also gives permission to the backup application to access the volume
and back it up in its frozen state. 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.

VSS coordinates between Requestors (backup applications such as Recovery Manager), Writers,
and Providers (components that create the shadow copies).
