SqlServerWriter error after Windows Serer 2008 R2 upgrade RRS feed

  • Question

  • Hi All.

    I have recently upgraded a Windows Server 2008 R2 to Windows Server 2012 R2.

    All works fine, except for the VSS SqlServerWriter.

    Backup software obtain this error:

    Cannot create a shadow copy of the volumes containing writer's data.
    A VSS critical writer has failed. Writer name: [SqlServerWriter]. Class ID: [{a65faa63-5ea8-4ebc-9dbd-a0c4db26912a}]. Instance ID: [{0167efa9-1d4b-4405-91f9-68db8a1ef164}]. Writer's state: [VSS_WS_FAILED_AT_PREPARE_SNAPSHOT]. Error code: [0x800423f4].]

    Do you have any suggestion to fix this error?

    thanks in advance
