I use qemu-guest-agent inside of a vm and ensure that the mounts are noatime.  
You can then use the guest agent to issue a freeze and get consistent rbd snaps 
of the backing devices.  Those snaps can be exported, preferably differentially 
to skip over the unused portions, off to some other storage.
