this issue has been boggling my mind for the past few days case number 05386803.
We got a customer backup for three seperate hyper-v hosts, from which 2 of them run into the error that the integration components are out of date.
There has been no changes to the servers except for maybe updates but even then, it just started out of the blue. Backups sporadically fail with that exact issue, retry's seem to work.
So far we tried upgrading them via VBR but also tried reinstalling the hyper-v integration on the host itself, issue still appears. Has anyone had this issue? Reinstalling the components just doesnt seem to really do anything.
I see in the case that you have another remote session is scheduled for next week.
Please keep working with our support engineer and keep us posted if they found a solution to this issue.
