Because last time it happened you had 1.) to call in an old consultant/employee 2.) that you know is now unavailable. The first part of that has been true at especially one place I worked though and while luckily he was still available it was still terrifying since he had left behind a proper Rube Goldberg machine. If he had been unavailable we would have had spent days and would probably just have had to recreate it from scratch (I watched him closely while he fixed it and it was a mix of at least from the top of my head: undocumented services, certificates that were expired, accounts with passwords that were unknown.) I've also experienced to be the one that was called to because the IT manager remembered that I used to be the guy who knew how to fix a certain problem with Sybase Adaptive Server Anywhere. I had documented everything I ever knew and could think of about it but it turned out someone there had "cleaned up" a bit.
