Back up software for mac?

I currently have a .mac account that's about to expire. The only thing I use it for is the scheduled backups to the idisk and an external hard drive. I don't want to pay $100 for another year since I don't use any of the other features. So--can someone tell me what I should use to replace this? I want something that can schedule a weekly full backup and manual when I choose, and to do so in incrementals when appropriate (if that makes sense). I'm willing to purchase something, I just don't want to 'rent' it any longer.

I know I could drag and copy manually but I like scheduling it for the middle of the night.

Any reccomendations would be appreciated
Thanks

Are you talking about online backup solution or you willing to buy something like external HD? I use Lacie Porshe 500GB, and it comes with bundled software SilverKeeper for mac. That's how I backup localy.
Sorry if I missunderstood question

Thank you Vlad, that does help. I'm not wedded to online, just want comfort knowing my back ups are running to an external HD on a regular basis (along with CD/DVDs for important stuff that I do manually). I'm looking to buy more external HD so I will check that one out. Thanks much.

I use chronosync, works amazing, and i even have it set up to help sync my laptop and desktop, as well as do the required backups nightly.
