Best Back-up Application on Mac OS X

These are the criterias that would satisfy the user of the application:

• Light-weight
• Easy and user-friendly
• Fast processing
• Least amount of errors

I have already tried Time Machine but the goal here is to not use it.
I have also tried Carbon Copy Cloner and SuperDuper!

If you know of any better alternatives please let me know or if you feel which is the best.
Thanks.
