I have just written a recursive backup program, and used a slightly different exclusion
procedure:
$exclusions = array ('...drupal' => true, 'Images' =>'true', .... );
if (!isset($exclusions[$file])) { [copy file to backup ] }
This looks simpler, and therefore quicker, but I suspect it is just putting the complexity
out of sight!
