MS-DOS: Copy folders without overwriting files

A quick note on how to copy files and folders over without overwriting existing files. It's easy to say "Yes" and replace all files. What I need is something that synchronizes files on an internal hard drive to an external one. I wanted it to copy only the files that were new in the original folder and only copy those over (reason being, the archive is 4 terabytes and backing up only the changed files would speed things up).
Applies to:
- Microsoft Windows XP
- Microsoft Windows 7
- Microsoft Windows 8
- for Vista and Windows 2008 without XCOPY, try ROBOCOPY.
How?
We're going to use MS-DOS because I'm that old.
