Not to trivialize the matter but:

- wireless isn't as good as wired, if you have a choice

- what matters isn't the drive size but rather the amount of data that
  changes. If you add a lot of content regularly; you'll either have to not
  back that content up, or figure out a way to move it faster

- long ethernet cables aren't a bad substitute for wireless in many homes,
  as long as you're halfway careful with them. Even if you can't substitute
  them for wireless everywhere, they can alleviate some of the problems
  sometimes. How often does someone use the laptop while sitting on the
  couch? Just run a cable to there and teach them to plug it in. 

- set up a wired and wireless network on different broadcast domains (they
  should be anyway); when the machines appear on the wired network, back
  them up. Don't back them up when on the wireless network (especially since
  wireless uses a common collision domain, like a hub; so a backup on that
  network will constrain everyone's bandwidth).
