This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.
The best real time back up is setting up a raid with multiple hard drives. For scheduled back ups I used the default in 12.04 that is deja dupe I believe, but you can click the Ubuntu icon and pull up the dash and type "Back Up" and it should be the first on the list. It looks like a little black safe icon.
It works great for me. Hope this helps.
Here is a link on setting up a software raid. I would look at many before I made the jump into it to find out the best solution because there are lots of different options and methods.
