DPM 2010 Backing up Hyper-V issue RRS feed

  • Question

  • Hello everyone

    I seem to be getting this error for one of my guest servers when trying to back up all the guest servers on the host.

    The replica of Microsoft Hyper-V \Backup Using Child Partition Snapshot\guest on host.contoso.com is inconsistent with the protected data source. All protection activities for data source will fail until the replica is synchronized with consistency check. You can recover data from existing recovery points, but new recovery points cannot be created until the replica is consistent.

    For SharePoint farm, recovery points will continue getting created with the databases that are consistent. To backup inconsistent databases, run a consistency check on the farm. (ID 3106)

    An unexpected error occurred while the job was running. (ID 104 Details: The parameter is incorrect (0x80070057))

    I've look through all the event logs and found nothing out of the ordinary except for the following error above.

    I've also ran the vssadmin list providers to see if all the vss writers to ensure they are in a healthy state.

    Has anyone encounter this issue before?

    I am currently suspecting that the drive does not have enough room to create a VSS backup o as the VHD i am trying to backup has 3 200GB VHD while there is only 60GB of disk space left.

  • Hi

    Have you tried to stop the protection, retain the data, recreate the protection?

  • Yes I have tried to stop the protection and recreated it already.

    Does anyone know what is the required disk free for a VSS backup to be completed successfully?

  • According to TechNet 1 GB or more per volume

  • 300MB on each VM volume is the minimum where if usually fails.   Also, what else do you have going on at that time.  Problems that I have seen that may or may not be relevant are:

    Saturation of the DPM server NIC:

    Multiple simultaneous backups of the same volume by multiple protection groups.

    Saturation of the DPM Disk resource I/O.

  • I solved it with removing double backslash in virtual machine VHD path. It was something like c:\xxx\yyy\\zzz\ttt.vhd. How did you solve this?
