If you use a hardware Volume Shadow Copy Services (VSS) provider to back up Hyper-V virtual machines in a cluster that uses Cluster Shared Volumes (CSV) storage, you can back up multiple virtual machines System Center 2012 - Data Protection Manager (DPM) using from the same CSV and node in the cluster. To specify the number of concurrent backups that can run from a node, do the following:
Open the Registry Editor.
Navigate to HKLM\Software\Microsoft\Microsoft Data Protection Manager\2.0\Configuration\MaxAllowedParallelBackups.
Set the following values:
Value: Microsoft Hyper-V
- Value: Microsoft Hyper-V
This setting enables a maximum of three backups to run concurrently on each node. For optimal performance, we recommend that you do not use a value greater than 3.
