Hi all,
I'm running a luminous cluster with tens of OSDs and
the cluster runs well. As the data grows, ceph becomes
more and more important.
What worries me is that many services will down if the
cluster is out, for instance, the engine room is out of
electric or all ceph node are down at the same time, maybe.
Is there a best practice on remote disaster recovery?
I wanna backup the whole ceph cluster so that the services
will come back online asap if the cluster is down.
Thanks
