So i am at the point that i wwant to make back ups of my drives, which is better SD or CCC? what r the pros and cons of each or differences and similarities? I have a mac min a mac pro, and possibly a mbp 13.3" comming, so i would want to set everything up to do 1 complete back up of each computer, then incremental back ups 1 a day or each week? with out having to do much! Which is the best? thanks!
