Hello,

I discovered an 4 year old snaphot on a Windows 2016 HyperV Host at a
Windows 2008 R2 VM with 100 GB *.VDHX File of drive C:
and there is also
a 150 GB *.AVHDX File of drive C:

Do you think deleting the scnapshot via HyperV manager is without risk?
Do you think this actionplan make sense?

draft-action-plan:
a) check whether wbackup was running well on HyperV Host
b) shutdown windows2008 VM and copy all "hyperV" files on a separate drive
c) make a file-backup of windows2008 VM if possible
d) goto hyperV manager and delete the snapshot

DONE

    Hi,

    I agree with the action plan, it's recommended to backup the VM before deleting the checkpoint. Besides, before that, please check the chain between the avhdx file and the vhdx file, we may use "inspect disk">inspect parent:
