VSS Writers: System Writer - Waiting for completion

    Question

  • 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 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.
