Microsoft developed VSS (Volume Shadow Copy Service) as a common framework to resolve these issues. Available in Windows Server 2003, software and hardware vendors now have a common interface model for generating snapshots. The VSS framework specifies how three distinct components should interact. The three different components are the VSS requestor, writer, and provider. The requestor is the backup software, such as the Backup Exec Agent. The writer is the application software such as SQL Server or Exchange Server that pause to allow the snapshots to be taken. The provider is the specific hardware/software combination that generates the snapshot volume, in this case, the IBM System Storage DS Hardware Provider.
