Nope! That would be "BWAH HAH HAAWWWHHH!" It's right here on page three of the evil laughs textbook. That's what you get for sleeping in class.

If the servers were virtuallized (or, really, regardless of that), they most likely were making regular image backups to a networked storage drive. That sort of drive tends to fill up quickly, but, if it's not getting those images, anymore, the likelihood of the images being deleted for space goes down considerably. The people in charge of managing those sorts of things tend to be overworked, so it would be very easy for the images to be saved more from absent-mindedness than altruism or any kind of emotional or business attachment to them.
