HyperV Error

If you get this error within your HyperV backup report:

Failed to backup virtual machine "FCE85082-F72E-40F6-9FAA-341F2B84DB7A"., Reason = " Getting the mounted storage instance for the path 'Disk 1 3353.32 GB Bus 0 Lun 1 Target 1' failed.The operation failed because the file was not found."

This is because you have got a "pass through disk" configured.

This is not supported with the Safe Data Storage backup client.

My suggestion would be to perform a file backup of the guest. Or A StorageCraft (Bare Metal) backup of the host & guest.
