I think it's important to document anything, be it at home or for business. I've done good and not so good jobs with this at times, and you feel like a hero when it's well done and you suffer through reinventing things if it's poorly done. I agree you should have config files and backups, but like with work, I think it would be good to go through a "disaster" where you have to build a version of your config from an unconfigured environment. A colleague had built such a config for a small office (10 people), but it depended on a specific DNS that ... wasn't set up until 1/2 way through the config. It worked because in testing they were using the network with a DNS that was already working. Small things like that are hard to catch in a working environment.
