Appendix B: DPM 2010 Schema Extension

Updated: April 21, 2010

Applies To: System Center Data Protection Manager 2010

The DPMADSchemaExtension tool performs the following tasks to support end-user recovery:

  • Extends the schema

  • Creates a container (MS-ShareMapConfiguration)

  • Grants the DPM server permissions to change the contents of the container

  • Adds mappings between source shares and shares on the replicas

This appendix describes the classes and attributes that Data Protection Manager (DPM) adds to Active Directory to support end-user recovery.
