Two things...
1. You don't want to back up directories every time you do a backup:
   you want the directories backed up the first time, and thereafter have
   only files backed up.  Unix directories are just structural definitions,
   like empty files.  Repeatedly storing them on your server is only going
   to waste space.
2. Unless you have a compelling reason to cause everything in those
   directories to be backed up every time, I should think you would want to
   use Incremental backup against the directories, to back up only
   changed files, and avoid a lot of server overhead.
