  1. Thanks for the info. I thought I’d just add that in our case the problem ended up being that we were running DPM 2012 SP1 and it was getting these types of errors because we were trying to back up stuff off of a 2012 R2 Hyper V cluster. Apparently there are some compatibility issues. We upgraded to DPM 2012 R2 and backups of the VMs off the hyperV hosts are working fine again.

  2. It’s actually a nice and helpful piece of information. I am glad that you shared this helpful info with us. Please keep us up to date like this. Thanks for sharing.
