68344: Acronis Cyber Protect: Agentless backup of Hyper-V VMs finishes with a warning "Cannot take checkpoint for 'MachineName' because one or more pass-through disks are attached."

Last update: Thu, 2021-04-01 14:45

Symptoms

Agentless backup of Hyper-V VMs with pass-through disks finishes with a warning:

Cannot take checkpoint for 'MachineName' because one or more pass-through disks are attached.

Cause

Agent for Hyper-V does not back up pass-through disks. During backup, the agent skips these disks and adds warnings to the log.

Solution

You can avoid the warnings by excluding pass-through disks from the protection plan.

If you want to back up pass-through disks or data on these disks, install an agent in the guest operating system.
