script for copying new/updated files between 2 internal HDs

I have two internal HDs on my G5 using OS 10.2.8. Where can I find a script to copy image files that are newly created or altered on my boot drive to my backup, second internal HD? Or perhaps a good tutorial for a total newbie? TIA

A folder action can easily handle the newly added files. Here’s the basic code.

on adding folder items to this_folder after receiving added_items
	repeat with item_ in added_items
		try
			tell application "Finder" to ¬
				duplicate item_ to folder "path:to:target folder:"
		on error errMsg
			-- do something when an error occurs (if desired)
		end try
	end repeat
end adding folder items to

Folder actions do not operate on modified files. It is likely possible to write a stay open script (application) that can handle this but I have no sample code to offer.
