For now quorum lives on top of qcow*/qed it doesn't fit well with snapshot:
it a step before turning it in a block filter.
When the QEMU block filter infrastructure will be done (and I am willing to
help it happen) quorum will live on top of raw files and below qcow*/qed
this way snapshot should work fine.
