Hi Alexandre,
Thanks for the link! Unless I'm misunderstanding, this is to replicate an RBD volume from one cluster to another. What if I just wanted to back up a running cluster without having another cluster to replicate to? i.e. I'd ideally like a tarball of raw files that I could extract on a new host, start the Ceph daemons, and get up and running.

Yes, you can use rbd snapshoting, export / import
http://ceph.com/dev-notes/incremental-snapshots-with-rbd/
But you need to do it for each rbd volume.
Here a script to do it:

(AFAIK it's not possible to do it at pool level)

Objet: Full backup/restore of Ceph cluster?
_______________________________________________
Hi folks,
I was wondering if anyone has a solution for performing a complete backup and restore of a CEph cluster. A Google search came up with some articles/blog posts, some of which are old, and I don't really have a great idea of the feasibility of this.
Here's what I've found:
http://ceph.com/community/blog/tag/backup/
http://ceph.com/docs/giant/rbd/rbd-snapshot/
http://t3491.file-systems-ceph-user.file-systemstalk.us/backups-t3491.html
Is RBD snapshotting what I'm looking for? Is this even possible? Any info is much appreciated!
Thanks,
Chris
