Hyper-V Guest Backup Fails - Transient Error RRS feed

  • Question

  • Having persistent backup problem - Windows 2012 Hyper-V Host fully patched can't back up running VMs to attached USB disk - when I stop them they backup fine. Yes, I have the latest Integration Services loaded on them (there are 7 of them - a mix of W2K3, W2K8 and Windows 7 enterprise). I have rebuilt the schedule, re-registered the VSS Writer etc. No luck. Backup was working fine until the last patch cycle or thereabouts (not sure if this problem is related). No other errors in the system or application logs.

    Here are details:
