DPM–More of BMR (Error 0x80070057)

When doing the restoration for the BMR, it’s very important to note the following :

You can't do an image restore unless ALL the drives are exactly as they were. Meaning when I was using USB drive to initiate the recovery, it was counting that as a drive. So no go on using a jump drive to initiate the Windows Recovery Environment. That was what was the "the parameter is incorrect; 0x80070057" error.

So I figured a workaround.  Once you have selected the network driver to be installed and also the shared network drive where the DPM recovery image is stored, you then eject the thumb drive, before you click FINISH in the end for the restoration process.  That will do the trick.

Hope this helps you Smile.

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.

DPM – What is Initial Store ?

When you use the DPM to backup a Hyper-V Server, there’s a check box for Initial Store. What is that … you may wonder.

The initial store contains the security permissions for Hyper-V’s Authorization Manager (AzMan).  This is an xml file located in %systemdrive%\ProgramData\Microsoft\Windows\Hyper-V\. You only need to perform a restore if this xml file becomes corrupted or is deleted. 

Backing up virtual machines and the initial store are independent. You only need to back up the initial store if you are using the Authorization Manager in Hyper-V and don’t want to lose your settings.
