Backing up your computer

Do you back up your site? I backup all of my sites weekly. It can be a pain because I have to transfer the information off of my computer to a neutral site. I figure if my computer goes down, it won't help to have the backup info on that computer. I'm looking into something like Anytime@Anywhere online backup that will make it easier and more convenient for me to save my data.

My computer and all of it's info is important to me because it contains a lot of financial info as well as my means for making extra income. I have to protect my investments.
