I'm having issues on a Hyper-V Host. When the backup runs I'm getting this error:
Microsoft Hyper-V VSS Writer' writer status is invalid. State: FailedAtPrepareSnapshot, Failure: WriterErrorNonRetryable
Support ticket has been opened, and the suggestions are to disable integrations, and change the checkpoints to standard. I haven't made those changes because this happens infrequently. It started a few months back. In looking at the past month's backup I see 8 times it did this, while all the other days it worked fine (22 or 23 successes). I wasn't sure what changing those setting would do... impact-wise. Also, it seems unlikely that they are the issue since the jobs work like 75% of the time.
One more thing, if I run the job as soon as I get the failure email (withing maybe an hour) the job will run fine. I have never had a manual job fail.
I saw another post here similar, but it didn't seem to have a resolution. Anyone else having this?
I see that ticket has "Escalated to developers" status, and steps regarding integrations/checkpoints are a part of a standard troubleshooting procedure. I suggest to continue conversation in this ticket.
