I am trying to find software to save me some effort. I have an external HD that I store all of my pictures, movies, and music on. Currently I am searching through each of these folders and finding what doesn't match, and then copying over. There has to be a better solution. It looks like CCC can do this for me, but I wanted to see if there was a free version. Here is what I want the software to do in a perfect world. I want to be able to set "watched" folders. When I plug in external HD, it will check these "watched" folders for what has changed since last time. It will automatically copy these changes over to mirror "watched" folders on both HD's. Anyone have any software solutions?
