What Online Backup Service Do You Recommend?

About a month ago, I asked on Twitter for suggestions for online backup services as I’m tired of manually backing up and I never do it often enough. I was suggested Mozy, but I was also suggested a lot of alternatives. However I was leaving on a business trip basically the next day, so I never got around to reading the Tweets and they eventually slipped off my @mentions list.

So now I’m asking how I should have done it in the first place — on my blog. What online service do you use to backup your data? And before anyone suggests it, Dropbox is out of the running as it’s too expensive for actual backup (it’s great for sync though!).

Thanks!
