Carbon Copy Cloner is one of my all time favorite programs that takes the stress out of ensuring data security and redundancy. It’s a simple program that copies data from one place to another exactly when you want, and exactly how often you need it to. It completely takes the guess work out of dragging and dropping blocks of data from one volume to another; it’s perfect for photographers. We’ve all been victim to the dreaded dragging and dropping of folders onto hard drives only to manually match the exact GB’s from the source and the GB’s on the destination.
