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:
* Disable geo-replication
* Snapshot the Disaster Recovery cluster manually
* Rollback all of the RGW pools to the snapshot I want to restore from
* Manually restore objects from the Disaster Recovery cluster to the
Production Cluster, probably using s3cmd
* Return all of the RGW pools to the most recent snapshot
* Re-enable geo-replication
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?
Cheers
