bek volume corruption

Hi
I have an Azure VM with ADE enabled I have it backed up to Recovery Services Vault. I've just logged into the VM and its asking me to 'Restart to repair drive errors' and from checking the Event log there's lots of errors caused by corruption on the bek volume - "A corruption was discovered in the file system structure on volume..." and "The Master File Table (MFT) contains a corrupted file record"

Obviously I'm hoping the restart will fix this but in preparing for the worst I'm just wondering how this drive is handled during the backup/restore process? The documentation suggests that is is backed up but i feel like it only refers to OS and data drives and not to a restore of the bek volume itself. Can anyone confirm if this gets restored as part of a VM restore?

Thanks

    @Archer252 Firstly, apologies for the delay in responding here and any inconvenience this issue may have caused.

    If you are using Single Pass, then this is issue occurs, when ever you restore /stop/start or redeploy or reboot the BEK volume would created automatically
    If there is an issue with bek volume? Yes, it would get fixed with stop or start or redeploy or reboot

    Run the following command on Elevated command prompt:
    chkdsk /f <drive> [ Example: chkdsk /f F: ]
    After chkdsk is completed successfully, restart the server.

    This article describes the “Checking file system” error that you may encounter when you boot a Windows Virtual Machine (VM) in Microsoft Azure.

    Hope this helps!
