Editorial Now that everything is moving to the cloud internet, you might think that data loss is a thing of the past. Sadly, as the past few months have taught us, this actually isn't true; we first had the Microsoft/Danger disaster, and now we have Palm and Sprint facing a class-action lawsuit over data loss for webOS phones. All this raises the question: how safe is it to store your precious data on the internet, and do you really trust the internet?

"When cloud providers guarantee 5x9's of reliability,
Just for reference, that's about 5 minutes of downtime per year. There are other significant issues, of course. But a five nines requirement seems a bit excessive for most applications. And, of course, the truly relevant number is "How reliable they can be" - "How reliable your local Datacenter can be". "

5x9's isn't excessive if you're an enterprise and your entire business is riding on customer guarantees. Google and other companies like it don't get that. It's simply going to take some time before we reach that point. Not saying that it can't happen. But it's gonna require having adequate failover support, and nobody is investing in that kind of capability for Internet computing -- which remains at "sort of good enough". That may work for a lot of small businesses, though.
