An easier mechanism is to do the following:

	Once you have completed the original installation of your software
	create a file called ".epic_file" in your root directory.

	When you want to make a back up of the changed files you just run:

		find . -newer .epic_file -print | cpio ...

This way you don't have to go through the step of creating the links and you
don't have to worry about an update installation that removes the pre-existing
files instead of copying over them.

If you didn't create the ".epic_file" when you originally installed the
software, you can use "touch MMDDHHMMYY .epic_file" to creat it with the
appropriate date/time.
