Note
Some VSS-enabled backup software does not have a SQL VSS Requester for backing
up SQL Server databases through the VSS infrastructure and the MSDE VSS Writer. In
that situation, use the procedure for backing up databases with non-VSS-enabled backup
software.
To back up replicas by using VSS-enabled backup software
1. In the console tree of the backup program, browse to \Program Files\Microsoft
DPM\DPM\Volumes\Replica\ on the DPM server.
2. Select the computer for the replicas you want to archive or the individual protected
volumes.
3. Select the backup type.
Important
Consult your backup software documentation or contact the software vendor to
determine which backup types will not modify the replica data.
4. Select the media to which you want to back up the files.
5. Start the backup.

Backup Using Non-Microsoft Software That Does Not Support VSS
If your backup software does not support VSS or DPM, you must use DPMBackup, a command-
line 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.
Use DPMBackup to prepare files for backup when using non-VSS-enabled backup software.
DPMBackup is a command-line tool included with DPM that performs the following tasks:
• Creates and mounts backup shadow copies of each replica volume on the DPM server.
• Creates database backups of the DPM database (DPMDB.mdf).
DPM creates a mount point of the backup shadow copies of the replicas on the DPM server in the
folder \Program Files\Microsoft DPM\DPM\Volumes\ShadowCopy\. The backup shadow copies of
the replicas are organized by computer.
You can configure either your tape backup program or Windows Scheduler to run DPMBackup
before the tape backup program runs. The amount of time that DPMBackup requires to create the
backup shadow copies and database backups depends on factors such as disk and database
activity, but as a guideline, you can expect the tool to take approximately 2 minutes per replica
volume to complete the operation.
