The wip-rbd-diff branch has an early prototype of rbd incremental backup/restore. Currently it works like:
rbd export-diff myimage@to --from-snap from - | \ rbd import-diff - myimagecopy The import apply the update stream and then create the final 'to' snap (which is referenced in the stream itself). A filename can be used in place of -, naturally. It's still very rough around the edges, but it's passing my basic tests; feedback is welcome! sage -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
