Fabian, i map img to pve node and then i mount to this node:
# mount -t ntfs-3g /dev/loop0p1 /mnt/loop
# ls /mnt/loop
'$RECYCLE.BIN' Common Departaments Groups rba 'System Volume Information'
but file have little size, example virtio-win-0.1.262.iso over 700mb in really.

there is no "mapping a full backup", all backups are equal. you need to find out why passing through the loop device does not work, please provide the logs I asked for..

Fabian, can you write what logs i can attach. I'm a afraid to make a mistake.
 
the system logs of the VM (e.g., journalctl in case of a modern linux distro) and the host (journalctl as well). you can limit the time period with "--since ... --until ..."

Fabian, thanks for response. I map img to pve node. All exe\iso (large files) files have size 34byte.

Code:

we need to find out why pass through doesn't work as expected, so we need logs from when you try that (from both the host and the VM side)
 
those are still not the logs I am looking for..

the logs I want are
- journal of the PVE host where you do the mapping
- journal of the VM that you give the mapped loop device to

your logs show attempts to mount the mapped loop device on the PVE host, that is not what I am after..
 
could you maybe try with a lower index (e.g., the next "free" one in your VM config?)
 
instead of "scsi10", pick the lowest free scsi slot of your VM
