Lots of people "do backups", not many have a "disaster recovery plan" and very few have ever practised their disaster recovery plan. Years ago we had an intern for a time, and he set up our backup scripts on production servers. He left after a time, we deleted his user, and went on our merry way. Months later, we discover the backups had been running under his user account, so they hadn't been running at all since he left. A moment of "too busy" led to a week of very, very busy.
