Does Safe Backup Plus support backing up pass-through disks? - Safe Backup Plus

The answer to this question is No while Hyper-V supports passthrough disks.

Hyper-V itself does not support backing up passthrough disks (nor does it support replicating them). A Hyper-V backup of the guest machines can be taken from the host, but does not include any data from passthrough disks.

Workaround

You can work around this issue by either:
  1. installing Safe Backup Plus Backup inside the guest VM, and backing up the extra data at a file level (this will use an extra Device license); or
  2. changing your passthrough disks to be a real disk containing a large .vhd or .vhdx file. The "New Virtual Disk Wizard" in Hyper-V Manager has an option to convert an existing disk to a .vhd or .vhdx file.
