Do you confirm the following procedure?
Consider vdi 'wheezy' with snapshots 1,2
Snapshot 1 is the older one.
I have a full copy of snapshot 1
qemu-img convert -O qcow2 sheepdog:wheezy:1 /media/nas/whezy_s1.qcow2
I save all the increments
dog vdi backup -F 1 -s 2 wheezy > /media/nas/inc2.img
Considering a disater recovery
dog cluster format
qemu-img convert -f qcow2 /media/nas/whezy_s1.qcow2 sheepdog:wheezy
dog vdi snapshot wheezy
dog vdi list

# If we start the guest right now it would start as of snapshot 1,
so we roll back (ahead in this case: )
dog vdi rollback -s 2 wheezy
In case of more increments, repeat the necessary steps.
