Older versions of rbd export did not export the snap shots but the
export format 2 does include them if my reading of the documentation is
correct.

The export-diff can export everything by not giving a from snap
(--from-snap), my backup script uses this method.

I've not tried export-diff to see if it records the snap between the two
points.

But a simple script which exports with no from snap and then between
each snap would give you the result if it did not.

Really depends on what your trying to achieve.
