A new KB article by Microsoft solves an issue where a Windows 8.1 Client Hyper-V or Windows Server 2012 R2 Hyper-V virtual machine backup leaves the VM in a locked state.
Consider the following scenario:
- You’re running Microsoft System Center Data Protection Manager (DPM).
- You start a backup job in DPM to back up Hyper-V virtual machines (VMs).
In this scenario, DPM sometimes leaves the VM stuck in the backup state (locked).
A supported hotfix is available from Microsoft Support. To apply this update, you must first install update 2919355 in Windows 8.1 or Windows Server 2012 R2.
