VSS error on host-level backups RRS feed

  • Question

  • We have recently virtualized a Windows Server 2003 SP2 server into a Hyper-V 2008 R2 cluster, and as we're running DPM 2012 R2 we have to protect it on host-level as there's no agent support for W2003 in DPM 2012 R2. However, I keep getting the error below when running a consistency check on the server:

    DPM encountered a retryable VSS error. (ID 30112 Details: VssError:The writer experienced a transient error.  If the backup process is retried, the error may not reoccur (0x800423F3).

    There are a lot of VSS writers with "waiting for completion" status after a snapshot - System writer, NTDS, IIS, and FRS. The Hyper-V writer gets a retryable error on the host, but other VM's on the same host works just fine. We have also tried to move this VM to another Hyper-V host but with the same result. KB940349 is already installed on the server but it doesn't seem to help.

    Any ideas or suggestions are much appreciated!
