So what does everyone mainly use for their backups? I've never used Time Machine before but I've used SuperDuper! quite a bit, is the automatic backup feature on SD! better then TM? If so then I'd rather buy the full version of SD! then use TM. I just bought a 500gb drive so I'm going to be picking up another for my backup. For Time Machine should the drive be bigger then the Target drive or is the same size OK? What do you use and/or what do you prefer? Thanks.
