'rbd export' gives you the raw data, you can just pipe that into where 
you want it? E.g. 'rbd export -p cephpool export vm-XXX-disk-Y - > 
/mnt/usbdisk/file.raw'

Or if you want to overwrite your entire usb disk with it:
'rbd export -p cephpool export vm-XXX-disk-Y - > /dev/sdX' (make 
*really* sure you got the right device ;)

You should be able access snapshots with the '@' syntax, i.e. 
'vm-xxx-disk-Y at snapname'.

Hope that helps,
