Hi there! I see you're facing some tricky issues with your VMs. Let me try to simplify what's happening. You've set up VSS snapshots across two Windows Server 2019 hosts, but you're encountering errors where Hyper-V can't create the snapshot for certain VMs. The error code 0x800705B4 suggests a timeout during snapshot generation. It sounds like the backup process might be ongoing when it tries to finish. On one VM, especially the older Windows Server 2012 R2 instance, you're seeing hangs and freezes—rebooting seems to resolve the problem. The logs point to specific DPM errors, which can help pinpoint the cause. Have you checked if shadow copies are still enabled or if there are any pending operations? Also, ensure that the VSS agent is properly installed and configured on both hosts. Let me know what you find next!
