  • DPM 2012 R2  Backup job FAILED for some Hyper-v VMs

    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.

    All the vss Writers are in stable state

    Also Some Hyper-v VMs are not appearing in the DPM 2012 R2 Console When I try to create the Protection Group please note that they are not part of cluster.

    Host is 2012 R2 and The VM is also 2012 R2.

  • Hi,

    What update rollup are you running on the DPM 2012 R2 server ?  DPM 2012 R2 UR5 introduced a new refresh feature that will re-enumerate data sources on an individual protected server.

    Check for VSS errors inside the guests that are having problems being backed up.

  • I am using UR4 recently. I am planning to install UR5 but it will require reboot of all the protected server. All the vss writers are in stable state.

    When I go to the regedit in one of the VMs (whose backups are failed) I see registeries as shown below.

    And One VM is not showing up in DPM 2012 R2 console I dont Know Y?
