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?

While I agree the gene pool could use a bit more chlorine...what happens when one of these undesirables happens to jump the curb and take out a Stephen Hawking, Albert Einstein, etc? It's not just the individual hurting themselves which is what drives the lawmakers to action.
Personally I'm all for on-the-spot executions for any infraction, just watch out for the white fences. http://www.imdb.com/title/tt0708739/
I asked for a quick writeup and just kept it to what the communications person chose to include. Feel free to fire away on whatever topics you know him to be knowledgeable on.
Without being able to put too fine a point on it look for many of the accessibility changes to slowly roll out over the next couple of months. There is a high degree of priority shuffling right now as we fence w/ the corporate overlords about what defines "important".:)
well, then among the many "cool" updates on the way you will appreciate the work that is currently being expended to make low-bandwidth, small screen, iphone, etc, interfaces much less buggy and faster-loading.:)
Yes, it has been a painful migration. However, a complete rewrite of the FAQ is coming soon (with context-appropriate linkage from the rest of the site) along with a much more intuitive interface that allows for easier firehose use. You have already seen the very tip of the iceberg with this post by Rob, expect to many more things like this making the site easier to decode.
I know it hasn't been easy, but hang in there. Slashteam has some really cool stuff on the way.
The story tag is to distinguish stories from submissions and comments.
Among other datatypes. The firehose is our content delivery tool and pretty much any page is just becoming a filter on the firehose to display whatever data you are asking for. This allows us to do a lot of really cool things (both now and in the near future) and get some performance hits back soon.
By "real source" Mojo is of course referring to the fact that this submission was originally authored by him and submitted with the link to his own site, a link everyone can still see in the "related articles" which shows his original submission via the firehose. We aren't hiding the fact that we changed it, there was just a better link to be had. The unfortunate part of all this is a submission to Slashdot is merely a "heads up", we are not licensing your content, we are not purchasing an article. Ultimately our editors are going to choose both the summary text and offsite links that are best suited to represent the story for discussion by the community.
Now, this is not to say we don't value any submissions. We recognize that a certain amount of the driving force behind sharing a story is to get your own vanity link as recognition (although we do slap a big fat "nofollow" on there so no google-juice farming for you) so your name is linked to whatever you put in the "your site" field. In this case Mojo chose to link the top level domain of his site "http://hothardware.com/" which is linked to off his name. The "scoop", however, is what is most important to our readers and as an editor I feel the obligation to provide the absolute best possible content when available. In this case kdawson felt that article Mojo linked to was not as good as the Reuters piece. It happens a lot, get used to it. If a link or the summary text is not up to snuff we often rewrite/replace it for the good of the site.
Bottom line is you are submitting this story as a participatory member of a community, a community that is heavily in favor of ideals like open source and the freedom/sharing of information. While we value your contribution, I will always choose the site with better information and fewer ads when possible so that our readers have less drek to wade through to get to the meat. I mean honestly, few readers actually read the article before spouting off at the mouth as it is, I don't want to force that behavior with sub-optimal articles.
Sorry you feel you got burned, but a sense of entitlement in a community based on collaboration is something I just can't support. Hope to see you around in the future.
Frankly I'm a little tired (although not surprised) of the constant "omg just google it...I know lots about this subject so it is clearly not worth discussing" that seems to appear on the ask slashdots. I'll refrain from a tiresome rant that I'm sure we all can visualize without actually having to write it down.
However, wrt to this particular question, if you look closely he wasn't asking "how do I learn Java" or "where can I find info about Java", he was asking for those with experience to help direct his path of learning. It is precisely the abundance of Google results that probably prompted this question.
I know that on broad topics I am often frustrated by the abundance of crap that I have to wade through in order to get to the few gems that are worth reading. When it comes to long-winded textbooks and weeks-long learning processes I would be more than happy to allow someone with years of experience to direct me to the optimal path of learning (why going to school still makes at least a little sense).
I don't have the link on hand, but the funny thing was that many cops went on record in support of the speed trap websites because it accomplished what they were trying for anyway (just to get people to slow down).
Dwarf Fortress has been a decent time waster for offline play (great for airplane rides as it turns out).
For an online flash game I can't believe they left out Gold Miner, one of my favorite turn-brain-off-and-play flash games of all time. Great for those long corporate meetings...shhhhh.:)
No shipping policy. If you have an email address or other means of communication that we can use to hammer out the details and you are willing to pay over $2k at this point (/boggle) then you can win the auction.
Several bidders have written to ask about the charitable donation credit thing.
Unfortunately, the way that MissionFish.org (eBay's charitable works branch) handles the tax credit is all done auto-magically. So, when I asked if we could pass the tax credit on to the winner of the bid giving them both the item and the ability to do the tax write-off I was given the big "not a chance" answer.:(
So we greatly appreciate your bids, as I'm sure the EFF will as well, but we are unable to pass the tax credit on to the winner of the bid.
That statement was mainly to protect us against someone from crazy-mccrazytown on the moon from buying the item and sticking us with the shipping costs.
We will more than likely ship outside the US, just contact us directly to work out the details and get it cleared.
To the best of our knowledge none of these shirts have been worn and are clean and free of debris. Barring any errant burglars who broke in to wear our t-shirts of course.
