My wife and I both have MacBook Pros, and each MBP houses our iPhoto library for the sake of redundancy. We also try to keep our videos on each for the sake of a double back-up, but that's where the similarities end. From there we both use our MBPs for individual things. I need a way to back up both MBPs (preferably wirelessly), and I'm wondering if I can take an external HDD hooked up to an Airport Extreme; partition it for each MBP, and then point Time Machine to a given partition. I don't know if the longevity of the Time Capsules have improved any, but I'm also willing to look into that if need be. Even still, though, can those be partitioned to be used with multiple computers backing up wirelessly? Thanks for any info and help on this!
