For bup, there is something called Kup (http://kde-apps.org/content/show.php/Kup+Backup+System?content=147465 http://kde-apps.org/content/show.php/Kup+Backup+System?conte...), but I haven't tested it. For duplicity, there is a quite good ui in the form of deja dup (see http://www.howtogeek.com/108869/how-to-back-up-ubuntu-the-easy-way-with-dj-dup/ http://www.howtogeek.com/108869/how-to-back-up-ubuntu-the-ea...). It's really nice and easy to use, and if I recall correctly it's installed by default on Ubuntu.
