Here’s a dead good tool. Mozy is an online backup for both Mac and Windoze. You get 2GB for free or unlimited for $4.95 a month. I’ve been using it for about a week now and it just sits there doing it’s business. You can also encrypt your data with your own key so Mozy can’t even get at it.
If you fancy having a test or just want an extra 2GB of storage for free then click here.
