There are a number of different options for backup/disaster recovery solutions with Ceph, depending on what piece(s) of the platform you are using. For instance, the object gateways (think S3) from multiple clusters can be plugged together for multi-site replication. The CephFS and block device portions both have snapshotting built in that can be replicated offsite.

In the medium-term we're looking at having a way to replicate your entire cluster over the wire at the RADOS level (underlying object store). Longer-term we'd love to be able to offer WAN-scale replication for a single cluster and the ability to snapshot a cluster (or portions/pools therein) easily.

I hope that helps. If you have more questions hit me up on #ceph at OFTC.net IRC.

As one AC already pointed out, you should check out Ceph (full disclaimer: I work for Inktank now, the consulting services company that employs most of the core Ceph devs). Ceph is, at its heart a Distributed Object store, but we allow you to access in a number of different ways:

• * Native API
• * Via a RESTful interface that can handle native Amazon S3 and Swift API calls
• * As a thinly provisioned block device
• * Mount it as a POSIX-compliant file system via CephFS (although this is a bit rough for production environments just yet)

Josh Durgin has actually done some really interesting work in using the block device (RBD) to back Cinder which you can read a bit about here.

The cool part about Ceph is it was designed to be massively scalable (petabytes and beyond) and extremely fault tolerant / HA / etc. DreamHost actually just built out a huge production deployment of Ceph and OpenStack for their new DreamCompute / DreamObjects offering. If you have questions feel free to hit up the #Ceph irc channel at irc.oftc.net or poke me via email (my UN at inktank.com) and I'll see if I can't find the right person to help.

OpenStack really has some awesome potential, and we're excited about poking at it more with our semi-sharp Ceph-stick. Good luck.

Now that Ceph is gathering momentum since having been included in the mainline kernel, what other storage (or low level) advancements do you see on the horizon?
