A warning: I just noticed that when my MacBook runs from battery power, Time Machine will temporarily stop making back-ups. As this happens without a clear indication, I thought I'd submit this warning. If you look at Time Machine in System Preferences while on battery power, you'll see that there's no time indication for the next scheduled back -- but there's no reason shown for why there's no backup time. (I'm backing up to a dedicated partition on the same disk, but the same holds true for external drives.)

[robg adds: I thought I remembered reading this somewhere in Apple's documentation, but a search didn't find anything, nor is it mentioned on Apple's site. Logically, it makes sense due to the impact on battery life, but it's something you should be aware of.]
