I've read that story a few times and I'm always struck by how aware management was when that did happen. I suspect that, at least half of the places I've worked, if I (or anybody else) happened to be that one employee who had a backup on their home computer, they'd find it impossible to communicate that to upper management in any way. The whole movie would be shut down while somebody was saying "I have a copy over here! I have a copy over here!"
Were you actually in the situation? Because at practically all the places that I worked for (some of them smaller, some of them very big), I don't think this would be a problem if so much was at stake...
