Hi Shiv,

Found this in the oracle manual:http://download.oracle.com/docs/cd/B28359_01/backup.111/b28270/glossary.htm#CHDEJEIH

It is an extra plug-in functionality to classical RMAN

Volume Shadow Copy Service (VSS)

An infrastructure on Windows server platforms that enables requestors, writers, and providers to participate in the creation of a consistent snapshot called a shadow copy. The VSS service uses well-defined COM interfaces. See Oracle Database Platform Guide for Microsoft Windows to learn how to use RMAN with VSS.
