To make a total clone of a web site, use httrack... a couple of methods I've seen:
httrack "http://www.all.net/" -O "/tmp/www.all.net" "+*.all.net/*" -v
And to clone a drupal site, I found this worked for me:
httrack http://localhost/ -W -O "~/static_cache" -%v --robots=0
You might want to add "-/reply/" on that last one.
