Symptoms
If you have a single server that holds the Data Protection Manager (DPM) databases from several DPM servers, the overload on the servers causes the performance to degrade in Microsoft System Center 2012 R2 DPM.
Resolution
To fix this issue, set automatic refresh jobs to run every 30 minutes by setting the following registry key:
Registry key path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft Data Protection Manager\Configuration
Registry key name: InstallListRefreshIntervalInMinutes
Type: REG_DWORD
Base: Decimal
Value data: 30
Note If the key doesn’t exist, the default interval is 30 minutes.
Restart information
You may have to restart DPM Service (MSDPM) to apply the registry change.
