Does proxmox backup server backup hdds that are physically passthrough to a vm in promox ve

[nryolo]

i am passing some disks to true nas vm in my proxmox ve.
i need to know whether these disks can be backup-ed using proxmox backup server.

it depends how you pass them through. if you pass through the actual (PCI or USB) hardware, then no. if you use the physical disks as "source" for the virtual block devices (e.g., scsi0: /dev/disk/path,other_options in the VM config), then yes. the backup task log will always tell you which volumes are backed up or not. you can always use proxmox-backup-client directly (e.g., within the VM) to backup any disks you want - but then you need to take care of consistency yourself (e.g., by backing up snapshots instead of the changing disk itself).
