Hi Vsicherman,


Thanks for the questions, check out the information below: 


The virtual machines that have shared VHD, VDHK or VHD would need to be protected with the Windows FS iDA as this is a Microsoft limitation with Hyper-V 2016 and 2019 guest machines.

Additional Information

Hyper-V Server 2016 and Later

  • Backups of shared VHD, VHDX or VHD Set files are not supported for Hyper-V Server 2016. Checkpoint operations fail when backing up VMs that are configured with shared disks.
  • Backups of Hyper-V 2016 VMs use a production checkpoint operation to perform an application consistent backup. In some cases, the production checkpoint might not be created successfully (for example, because VSS operations are unable to present dynamic disks). In such cases, the backup continues as a crash consistent backup, completes with errors, and displays the JPR "Production checkpoint failed for the VM."
  • If pass-through disks are configured on Hyper-V 2016 virtual machines that are being backed up, those disks are not backed up and the backup job goes pending with the JPR, "Pass-through disks are not supported."
  • Note: If you perform an out-of-place restore for a virtual machine that was configured with pass-through disks, and the source VM remains in place, the restored VM might fail to start. To start the restored VM, remove the pass-through disks manually.

I hope this was useful
