Microsoft had recently release the Cumulative Update 2 (CU2) for System Center 2012. Part of it, it fixes the issues for Data Protection Manager 2012 (DPM 2012), Orchestrator (SCO 2012), Operations Manager (SCOM 2012), AppContoller and Virtual Machine Manager (SCVMM 2012).
Most of the fixes are for the SCDPM and the SCVMM.
The Descriptions of bug fixes are in this link.
But if you want to download the CU2 only for the SCDPM 2012 then go to this link directly.
Note : Remember to backup your DPM database before you perform this rollup update.
The issue of the VM Status of Unsupported VM Configuration (Error 644) is resolved with the patch for the SCVMM and SCDPM.
