Microsoft Volume Shadow Copy Service
Microsoft includes Volume Shadow Copy Service (VSS) in 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.
The HP 3PAR VSS Provider Software for Microsoft Windows coordinates between Requestors
(backup applications such as Recovery Manager), Writers (applications in windows services such
as Microsoft SQL Server) and Providers (components that create the shadow copies).
VSS Component Description VSS Component
The requestor is backup software that initiates the creation
of the shadow copy. Requestor
The writer is any application software that participates in
the shadow copy process and whose files and data are
included in the process. Writer
The provider is the storage technology that does the actual
shadow copy. Provider
