you can do that, but if any of its partitions are mounted during this and something writes to them, i suspect the filesystem could end up in a weird inconsistent state
>is there a way to verify it's a linux disk image? (should be a basic btrfs auto-partitioned setup)
you can mount the image on the destination and inspect the files
for an image like that, you should be able to do:
# scan it for partitions, or something
sudo losetup -Pf --show ./backup.img
# the partitions should appear under /dev/loop0 or similar here
lsblk
# example, to mount the first partition as read-only
# if the disk uses lvm then this is more complicated
sudo mkdir /mnt/backup
sudo mount -o ro /dev/loop0p1 /mnt/backup
# example, check files
ls -al /mnt/disk
# when done, unmount and remove the /dev/loop file mapping
sudo umount /mnt/backup
sudo losetup -d /dev/loop0

is there a problem with the disk?
