In for the long haul?

Dave Winer writes about the intrinsic fleetingness of everything you put on the web and what can be done about it.

I've been doing things to protect my writing. Yet, if I were to for whatever reason, stop tending my web presence, the whole thing would disappear within 30 to 60 days. One or two billing cycles before the hosting services cut off service. And then no more than a year before the domains expire and become porn sites or whatever.

For a more general take on the topic, you might want to read Mark Pilgrims post on long-term storage of personal data in which he asks the simple question: "How do you back up 100 GB of data per year for 50 years?"
