Description

It would be very usefull to have some sort of meganism in place which would ensure that the image you're importing a RBD diff upon is actual the right image in the right state.
Perhaps a checksum of the last N bytes could be compared between the source and dest image. Or perhaps something even smarter... Checksumming an entire 128GB image would take too long i guess..

This feature would be usefull for backup your entire collection of RBD images to a different (offsite) pool.
