Appleinsider:

This is a showdown between four of the best backup utilities and there will be a winner. However, the winner isn’t going to be one of these, it’s going to be you. We’re not looking for app we can crown the best and walk away for a year, we’re looking for the very best app for you and exactly what you need to do.

Any of these would do the job —but there is one that is better at it for you than either of the others. That said, there is a different one that’s better for your friend, colleague, partner, spouse, or relative. Let AppleInsider save you time picking from one of these four.

I agree that Time Machine is the easiest backup to do and the one I recommend to people who don’t do other backups but I’ve been burned a couple of times with it so I also do backups with SuperDuper and Carbon Copy Cloner – both great apps.
