DPM–Backing Up Hyper-V (Consistency Check Error)

Today I had an issue of backing up the Hyper-V through the DPM 2010.  The agent is installed into the Hyper-V host.  There’s also ample of space in the drive where the VHDs resides.  The same drive also caters for the snap shots. 

When I execute the Consistency Check it states that DPM failed to synchronize changes for Microsoft Hyper-V \Backup Using Child Partition Snapshots\VMServername on Hyper-VServerName because the snapshot volume did not have sufficient storage space to hold the churn on the protected computer (ID 30115 Details : VSSError : Insufficient storage available to create either the shadow copy storage file or other shadow copy data. (0x08004231F))

Status is Failed.

Therefore I carried out the steps below to have it working.

Step 1 (to be perform in Hyper-V Host)

• Open the the Registry.
• Add in the key :
  HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft Data Protection Manager\Agent\UseSystemSoftwareProvider

 

Step 2 (to be perform in the DPM Server)

• From the Command prompt (Run as Administrator), key in the command to stop the DPM and restart the DPM services.  The command are as follow :
  
  net stop dpmra
  
               then to start the DPM service
  
  net start dpmra
  
  

Perform the Consistency Check once more.  Once it’s completed, then you can Create recovery point for restore.

Thank you and hope it helps you.
