Mozy Blog: Probability is Fun
So I was wandering around looking at stuff having to do with distributed backup storage. One of the solutions available that seems highly regarded is Mozy. I don't know much about Mozy yet, such as where they actually store your stuff, but I looked at their blog and found this Monty Hall post.
Since the Monty Hall problem twisted my brain pretty severely back when Marilyn Vos Savant raised hell with it in Parade Magazine a dozen or more years ago, and this is about the best explanation I've seen, here it is.
Now to check out Mozy some more. So far my backups are primarily periodic disk images and differential updates, with a few files also backed up online using GoDaddy's Online File Folder service. This works fine but it seems Mozy, AllMyData and various others have good ideas, too.
