You should look at FileUtils::cp_r with the :preserve option. It's  
not the same as rsync by any stretch, but it should be fairly similar  
assuming you didn't need --delete or --include/--exclude patterns. If  
you do need those, then the source of FileUtils is probably a pretty  
good place to start rolling your own since it properly does symlinks,  
permissions, times, and other metadata.
