Backing Up DPM by Using Third-Party Software
The process for archiving the replicas and databases by using non-Microsoft software differs
depending on whether the backup software supports DPM and the Volume Shadow Copy Service
(VSS).
Backup software that supports DPM is specifically designed to work with DPM and will support
the DPM VSS Writer service (DPM Writer).
Backup software that supports VSS uses VSS-enabled file system shadow copies but does not
operate with the DPM Writer service. This software has two limitations compared to software that
supports DPM:
• Archive and restore operations are more complex than they are when using software that
supports DPM.
• The software that supports VSS organizes the archived replicas so that they appear to have
been backed up directly from the DPM server. Organizing the backup in this way can make
the process of restoring data less intuitive.
When you use backup software that does not support VSS, you cannot back up directly from the
replicas. Instead, you must use the DPMBackup tool to create backup shadow copies of the
replicas and database backups of the DPM database, and then use the backup software to
archive the backup shadow copies and database backups to tape.

Backup Using Non-Microsoft Software That Supports DPM
The optimal way to use non-Microsoft software to archive the DPM replicas and databases is to
use backup software that is specifically designed to work with DPM. The principal advantages of
software that supports DPM are:
• The archived data is organized in a way that makes restore operations intuitive and
comparatively simple
• The number of steps involved in archive and restore operations are minimized
The following procedures provide general instructions for archiving DPM databases and replicas
when using backup software that supports DPM. For instructions on using the backup software,
see the documentation for the backup software.
