Take a look at Chronosync, it will not only do what you want, it will store a small sync file after you do the initial sync, so you can then do subsequent syncs with a double click on the Chronosync file, and it will be EXTREMELY fast as it compares the previous state with the current state and then only updates the files that have changed. It isn't free but is very cheap, and after you buy it you get the updates forever for free.
I've been using it for years. I use it to backup my own data folders to other drives.
