My dad's always used the drive duplication function on Retrospect 6. However, due to his recent hardware updates, it's no longer possible. The main reason he stuck that long on that particular version was because he allowed him to duplicate the drives while at the same time still keep the timestamps on the files (his preference). He tried using other utilities but they always overwrote the timestamps as the date of the duplication for everything.
With being said, I was wondering if there is anything on the market or open source that has the ability to both duplicate a drive exactly down to the timestamp of the files original creation date.
