Frozen

Symptoms

The following critical alert is displayed when backing up Hyper-V host and virtual machine(s) on it:

The running backup has not shown any progress for some time and may be frozen

Cause

Most likely cause for this alert is that VM backup is queued as it is waiting for host backup to be completed.

Error message text will be improved in the future product releases.

Backup task status is displayed as "Queued" and never completes.
