That's easy: rsync with --link-dest so that all files that aren't changed are hardlinked. Then to 'tar' all changed or new files you want a list of files without hardlinks as those are the files that where changed or new(*): find <dir> -type f -links 1 > files.lst tar <options> --files-from=files.lst *: I'm assuming hardlinks aren't used within the source-directory. Otherwise find would skip those files too as they would also have more than 1 link. Also symlinks and special-files are excluded by the example.
