Veeam v7 backup Hyper-v VMs fail:Unable to create snapshot RRS feed

  • Question

  • I am using Veeam Backup & Replication to backup Hyper-V VMs。

    1、The use of two hosts of the Windows Server 2012 system,
       Veeam is installed on a host computer, virtual machine installed on another computer。
    2、Adding a Hyper-V Offhost Backup Proxy.
    3、Creating Backup Jobs,At the Guest Processing step of the wizard, select the “Enable application-aware image processing” check box.

    **It fails when trying to backup Hyper-V VM.This is the error:

    (1)Error:
        Unable to create snapshot VSS Hardware Provider on Hyper-V Offhost Backup Proxy. (mode: Veeam application-aware processing). Details: Writer 'Microsoft Hyper-V VSS Writer' is failed at 'VSS_WS_FAILED_AT_POST_SNAPSHOT'. The writer experienced a non-transient error. If the backup process is retried, the error is likely to reoccur. --tr:Failed to verify writers state. --tr:Failed to create VSS snapshot. --tr:Failed to perform pre-backup tasks.

    (2)running “vssadmin list writers” to see

       Writer name: 'Microsoft Hyper-V VSS Writer'

       Writer Id: {66841cd4-6ded-4f4b-8f17-fd23f8ddc3de}

  • Notes:
    **But if you don't select the “Enable application-aware image processing”,the backup job completed successfully.

    **if you select the “Enable application-aware image processing” ,and Hyper-V VM system is Windows Server 2008 ,the backup job completed successfully.

    question:
    1、Is it right? Windows Server 2012 does not support offhost backup,with select the “Enable application-aware image processing”.
    2、What can you suggest?

    Thanks!!

    Nope. It’s certainly supported.

    From my perspective, the best option you have is to open a ticket with Veeam support team and provide them with required information. Based on my experience, Veeam support team does its best in addressing issues, understanding the issues’ causes, figuring out potential workarounds, etc.

    As far as I know, you can open a ticket at the following site:

    Kind regards, Leonardo.
