No such issue on PVE7.3.

Same issue on my end. Unchecked the backup option from the passthrough disk and backup executed no problem. All my VMs with disk passthrough are behaving this way.

Hi,
thank you for the report! This is an oversight for passed-through disks. A fix has been sent the the mailing list.
EDIT: a version with the fix, i.e. qemu-server=7.4-3, is available on the no-subscription repository.
