Hyper-V guest Backup in VSS

Hi folks

 

Backing up a VMGuest a Windows 2016 server (latest greatest) by using the VSS function. I use a 3rd part product called Veritas Netbackup, spoken to them they are clear that this is not a netbackup problem but a Microsoft problem. 

 

OK So I have one Winserver guest 2016 that backups fine (on a hyper-v 2012r2 cluster) and I have another that I need to do "off-host" backup which will give me the "freeze" saved state enviroment. Those server are similar to each other, disk/firewall/tools/ and so on .. but the main diffrence is that one is in the DMZ. When backing the host in "hot state" it gives me an error: 

"2017-maj-29 11:18:37 - Critical bpbrm (pid=7792) from client bkbupdmz01: FTL - vfm_freeze_commit: method: Hyper-V_v2, type: FIM, function: Hyper-V_v2_prepare

2017-maj-29 11:18:37 - Critical bpbrm (pid=7792) from client bkbupdmz01: FTL - snapshot creation failed, status 4201

- This error comes from netbackup-veritas. 

 

Any one have a clue?

    Hi Pontus,

     

    What happens if you try to make a production checkpoint from the Hyper-V Manager? Check settings on the VM what kind of checkpoint is made.

     

    Do you get an error when creating the checkpoint?

     

    Regards,

      Hi there mr Ervin Van Dijik

       

      Thanx for answer.

      I have made the checkpoint from the hyper-v-manager. The checkpoints was created fine..

      But it was a less than 10sek frezze of the VM, when it were creating the checkpoint. And i saw the % build of the checkpoint. It release the freeze mode around 85% done of the checkpoint. 

       

      I couldnt see any error creating the checkpoint. 

       

      How can i see "what kind of checkpoint is made"? in hyper-v Manager?

       

      regards Pontus

        Hi Puntos,

         

        You can check it in the Hyper-V manager, go to the settings of the VM and go to Management - Checkpoints. Check also under Management the Integration Services, is the option Backup (volume shadow copy) checked? If this is checked (the default) then the VM is using VSS to create a checkpoint. If you want a "freeze" of the VM (paused state) then you must uncheck it. But personally, I think it’s better to use the VSS option.

         

        Regard,

         

        Erwin
