Can you give us more details about the problem you are facing off?
Is this a VM backup you trying to run on a Hyper-V environment?
Anyway, it sounds not enough space on D disk.
That sounds like your repository has run out of space which in turn can lead to data corruption depending on the type of backup job you are running. I.e. You might have an orphaned backup chain where it may have not saved data correctly.
I would say a space issue, how much free space is left?
I would second the space issue.
Yes that is right it is the space issue. Thanks for the response
