Yup. I used to teach my CAD students that MOST folks learned to back up their work AFTER the first catestrophic event.
The community college was very susceptible to power outages. I cannot count the number of times on seeing rain coming in, I would pop into the lab and say "SAVE NOW" only to be iterrupted by darkness.
But, the bright side is that you'll put it back together MUCH faster than before and it's a good review of the skills.
