> You're picturing some massive server failure, but not the more likely case of your Google account being disabled for any random reason, which has happened to more than a few people. As Gmail gains more users, you become that much less important to them.

"more than a few" is probably still in the ten-thousandths of percentage points if that. Some can't, but I can live with those odds.

And as Gmail gets more users, I'm guessing the odds get even better, particularly with so many of these new users being tied to Android. Google has a lot tied up with making sure things don't go south.

And then there's services like backupify.
