I think the previous responses are great but i would emphesise the 'Do' part of the equation. As a DBA your really paid for that couple of percent of your time when everything has hit the floor, the business is screaming for blood and they need someone with a cool head to put the pieces back together again. This takes someone who has 'Done' the relevant steps not just seen them in the book. The books don't show the worst case scenario's and can't prepare you for that feeling when your stomach drops as you are informed its all gone bad.
