The Volume Shadow Copy Service (VSS) provides the ability to create a point in time image (shadow copy) of one or more volumes that can be used to perform backups. The service is also used during restores of applications. After the VSS service is initialized, VSS requester applications can perform backups and restores in cooperation with VSS writers that manage application data to be backed up and VSS providers that create and manage shadow copies.
