VSS Backup Configurations

There are a number of conventionally supported backup types—incremental, differential, and full—that VSS is aware of, as well as a backup configuration peculiar to VSS.

In defining a backup configuration, a requester and the writers on a system indicate how data will be written to a storage device, how the shadow copy mechanism will be deployed, and what information needs to be saved. Interaction between writers and requesters is determined by the type of backup a requester wants to perform and the kinds (or schemas) that each writer can support:

• VSS Backup State
• Writer Backup Schema Support
• File Level Schema Support
