S3 fails too, right? Didn't they have an internal network issue this year, and go down for hours?

Anything you haven't tried, doesn't work. That's a truism in computing. I don't think Amazon tries failing-over entire data centers very often (have they ever?), so when it needed to happen, it didn't work.

Anyway, I'm thinking this guy has only to back up his photo store about once a day to (something big) and put it in his bank box, and he's good to go, at least for a photo site.

(Aside) I wonder if this is more accurately stated: Anything you haven't tried recently, doesn't work. Even if you have tried it recently, that's no guarantee.

Or, to paraphrase Hofstadter's Law, the probability of something working some time after you last tried it drops surprisingly quickly, even when you take into account this rule.


Amazon fails over data centers at least once a year in fire drill testing. Amazon has more backups, testing, and monitoring than 99.9% of small or midsized organizations.
