Configuring VSS for IntelliSnap Backup on Windows

 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.

Before You Begin

  • You need to install the VSS Software Provider along with Oracle Data Agent to perform IntelliSnap backups.
  • To perform VSS IntelliSnap backup for Oracle 10g, you have to install the Oracle VSS Writer. (metalink id 580558.1)
  • The snapshot Control and SP file locations should be snap-able.
  • Volume level Snaps are supported.
  • Database volumes must be on one of the supported storage arrays.
