I've looked into this a bit, and the
best I've come up with is to snapshot all of the RGW pools. I
asked a similar question before: http://comments.gmane.org/gmane.comp.file-systems.ceph.user/855
I am planning to have a 2nd cluster for disaster recovery, with some in-house geo-replication. I haven't actually tried this yet. I just setup my development cluster, and this is on my list of things to test. The basic idea:
I have several layers of safety above this, so this process is meant to be a last resort after several layers of human+code errors. In theory, it shouldn't ever happen, but we all know how that goes. I would like to discuss how RadosGW snapshots might work, but there doesn't seem to be much interest at this time. The ability to use RadosGW snapshots is somewhat niche. Hi, is there any way to create snapshots of individual buckets, that can be restored from piecemeal? i.e. if someone deletes objects by mistake?
