Updated: January 15, 2013
Applies To: System Center 2012 - Data Protection Manager, System Center 2012 SP1 - Data Protection Manager
If you are using the default system VSS provider and want to begin using the hardware VSS provider, you must do the following:
Install the hardware VSS provider on the host computer and ensure that your Storage Area Network (SAN) is configured for hardware snapshots.
Delete the %Programfiles%\Microsoft DPM\DPM\Config\DataSourceGroups.xml file from the System Center 2012 – Data Protection Manager (DPM) server.
Set the following registry key on the DPM server:
HKLM\Software\Microsoft\Microsoft Data Protection Manager\2.0\Configuration\MaxAllowedParallelBackups
To complete this process, you must run the Modify Protection Group Wizard for each protection group that protects the virtual machines on this cluster.
