I think you've got the wrong idea. You need to place %p and %f in your
command-string, and the server replaces them with the correct path/filename.

So - %p will be the full path to the file the system wants you to
archive and %f is just its name. Re-read section 23.3 of the manuals and
start off with the example commands perhaps.
