I definitely think we should keep Rule 2 (backups) and 3 (verify your backups) separate. I've been seriously burned by the lack of good backups. OK, it wasn't me personally, but it was the company I worked for that managed client websites. It happened when a one-in-a-million chance failure mode of a storage array occurred, where the whole unit failed and all the arrays were lost. The best backups attainable were several months old, and the client whose data was lost did not keep backup copies of their own. It took a week of several admins' time to scan the available backups and find the ones that were good and could be used.

SO, I think it's important enough to warrant having its own line item.

Aside from that, I don't know about any of you, but I'm going back to a "computer free" weeknight, where, for one night during the work week, I don't turn on the computer once I've gotten home. If you're not on call, this is a good way to free your mind and forget about the issues of the job, if only for a few hours. Naturally, it's a little easier to do on the weekends (and should be mandatory), but if you do it also between Monday-Friday, it can really help. If you're not so sure about this, think of this: If it's important enough, they'll call!
