Liberato, I understand perfectly your question. I too have the same problem. I found that while SuperDuper! is perfect for a full backup of my drive, it's not really easy to use for backing up those little important daily folders...
I recommend
SynchupX from Freeride coding as a junior partner app to SuperDuper!. It has the same simplicty as SuperDuper! and is in no way a "competitor" to SuperDuper! -- in my point of view - I hope Dave will agree
Sincerely, Martin.
