If this feature works, I suppose we can have "incremental backup RBD(2 copies,SSD based) to Rados ( 3 Copies,HDD based) " to achieve higher HA with quite a few extra cost :) -----Original Message----- From: ceph-devel-owner@xxxxxxxxxxxxxxx [mailto:ceph-devel-owner@xxxxxxxxxxxxxxx] On Behalf Of Sage Weil Sent: 2013年3月26日 7:39 To: ceph-devel@xxxxxxxxxxxxxxx Subject: prototype incremental rbd backup 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 majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html ?韬{.n?????%??檩??w?{.n????u朕?Ф?塄}?财??j:+v?? ? ???2??璀??摺?囤??z夸z罐?+?????w棹f
