This method allows for replicating the file and folder contents of an entire data drive, to an external drive or a second internal drive of adequate size. | While individual shared folders can be replicated using Services, Rsync, a more efficient approach is using an Rsync Command line, in a scheduled job, under System, Scheduled Jobs to mirror a drive.
