"Hello, I'd like to backup the Internet please...."
Yes, we all keep our data in multiple places so that if we lose one, we still have a copy. But this incident proves it is not just the data that is important, but the context of it too.
So all the links, comments, friends, etc, suddenly become part of the data. If it's important, then you should back it up.
But how? How do you backup not just your own, but everyone else's Facebook, Twitter, El Reg, comments, wikipedia content, etc, etc, etc, etc, etc, etc, etc, etc, etc
If you're paying for something, then you can negotiate/expect a certain level of service (T&Cs). If it's free, just how do you backup the Internet?
Before you choose to write some tyrannical reply, I'm simply pointing out the problem - I'm not criticising any person or company. And it ain't an easy one to fix!
"Houston, we have a problem!"
