Volume Shadow Copy Service (VSS) is an infrastructure on Windows server platforms that enables applications to create shadow copies. A shadow copy is a consistent snapshot of the data held on a volume or component at a well-defined point in time. It provides a Windows-specific interface that enables coordination between requestors that back up data, writers that update data on disk, and providers that manage storage. In our case, Oracle iDataAgent works as a requestor, Oracle VSS Writer works as a writer and VSS Provider works as a provider. Oracle iDataAgent supports hardware providers.
