@crashplan now has an unlimited online backup plan for individuals and families. The pricing is very reasonable, best deal for families 3yrs for $180 (eqv. $5.00/mo) and for individuals 3yrs for $125 (eqv. $3.47/mo).

I've been considering setting up CrashPlan in the data center and my brother Michael has already set it up at his house and is really liking it. I haven't used their service yet, so I can't endorse it, but it is definitely on my short list of technology to get to know.
