    Error : The specified component was not reported by the VSS writer (Error 517) in Windows Server 2012 Backup

    In Windows Server, it is possible to perform Backup of your system and even Virtual Machine in production. Yes Windows Server Backup is a really good solution for backup the Hyper-V virtual machines. But “The specified component was not reported by the VSS writer” error can sometime appear and failed all scheduled backup.

    Failed_Backup

    Today most of the company are using visualization solution (Microsoft, Citrix, Vmware …) in their infrastructure. I’m personally using the Microsoft solution named Hyper-V, due to the fact that it is included in Windows Server. After many hours of hard-working in my lab, I wanted to backup all my virtual machines. But one day, the error 517 came.

     ERROR DESCRIPTION

    One day, without any reason, an error message appeared “The specified component was not reported by the VSS writer” for all my virtual machines.

    RESOLUTION AND DOWNLOAD.

    After some research, I found that the problem was connected with Microsoft Shadow copy Service. I decided to delete all shadow copy in my host and I was able to backup all my server again.

    I used those commands line in a Powershell window:

    Order
    Command
    Description
     
    1 DiskShadow Connect to DiskShadow tool
    2 Delete Shadows all Delete all shadows copy
    3 list shadows all check that the list is empty
    4 Exit Disconnect to DiskShadow tool  

    Once, the command has been executed, you should be able to relaunch your backup.

    WSBSuccess

    HOWEVER, THIS ERROR CAN STILL COMEBACK!

    You have to delete again manually the Shadows copy or you can execute my script (DeleteShadows). The instruction are include in the rar file.
