World Edition MAC backup question

I have a MacBook Pro and just need the Word Edition 1tb to back up my harddrive wirelessly and enable it to be back itself up and the world book be partitioned to back up itself (World Edition)?  Can anyone give me step by step directions to make this happen?  Also should I use time capsule or the WD software?

Time Machine is the definiive answer! Works like a charm! If you ever have a harddisk crash, need to reinstall or replace your harddisk, this is very easy if you have a Time Machine backup. I have done so several times.
