The further change of moving backup to be a one block-copy call will make copying chunk-size and cluster-size two separate things. So, even with 64k cluster sized qcow2 image, default chunk would be 1M. Test 219 depends on specified chunk-size. Update it for explicit chunk-size for backup as for mirror.
