  • VSS Writers: System Writer - Waiting for completion

    Hi,
    We have Windows Server 2003 R2 in our environment and we use EMC Networker 7.4 to take backup of these servers. We take the system state backup of these servers with the help of a feature in Networker called VSS Save sets.
    Now randomly in certain servers this VSS backup fails while the file system backup (like C:\. D:\) occurs successfully. While investigating the VSS backup failure issue we observed that VSS backup fails when the System writer (by issuing "VssAdmin list writers" command) is in "waiting for completion" state. VSS backups are successful on those systems where system writer is in stable state. I have googled a lot to resolve this issue and applied all the relevent solution by applying MS pathes related to VSS, registering dlls etc but the issue still persists. If we reboot the server then it solves the issue for time being but after few days it surfaces again. I have also tried to stop/restart the MS Software Shadow Copy Provider service on the affected server but the System writer still remains in Waiting for Completion state.
    Please find the the output of the Vssadmin list writers command of one of such affected server below:

    Please tell me how can I make the System writer into stable state without restarting the server.

    Re: VSS Writers: System Writer - Waiting for completion

    Have you tried re-registering your VSS DLLs?

    There is actually a fix from Microsoft for this ;

      I had an issue with this but it was related to system state backups using NTBackup. It was the same problem, though.

      I had also run through the patch management exercise and the system was fully up to date VSS-wise.

      I solved mine by rescheduling the system state backups to be completed at a different time. They had been set for 6am and 6pm but changing it to a different time fixed it. I still have no idea why this worked.

        Hi,

        Sorry for the late reply.

        Yes, I have already tried to re-register dlls, applying hotfixes realted to VSS.

        The issue still persists.

        I have tried all the solutions available in the internet but no result. As this issue is happening in mutiple servers randomly so I am really concerned to solve this issue permanently.

        According to my investigation if the system writer is in "waiting for completion" state the backup will fail.

        So is there any way I can make the system writer status in stable state. I have tried to restart the MS Software Shadow Copy Provider service. But no result.

        Please Please please help me.

        Regards
