Volume Shadow Copy Service (VSS) Writer
The Oracle VSS writer allows Oracle Database to participate in VSS-initiated backup and recovery on Windows 2003 and above. VSS is a Windows infrastructure composed of three participants:
Requestors - management applications that initiate backup and recovery
Writers - applications that own the data
Providers - storage/hardware applications that coordinate the reading and writing of the data to appropriate storage
Several leading backup and storage vendors currently provide requestor and provider applications. With the Oracle VSS writer, customers can reliably back up and recover Oracle data in a VSS environment, which interoperates with these vendors' components.
