Google offers a lot of things, and I mean a lot, but this isn't really one of them. And yet, in a fashion they do.
A good friend of mine recently lost a rather good blog post due to a server issue (it was on a Linux box, so I'm not sure how that could ever happen ;^) and there wasn't a backup.
In a moment of brilliance (or just a misfiring synapse) I suggested he do a Google search for his lost post and see if they had a cached version of it. And low and behold, they did, crisis averted. If I could come up with great ideas like this more often, having a job would be unnecessary :)
