Hey there,
Welcome to the forum, and Linux! You're in for a cool ride, lemme tell you that!
You can clone your drive, there is a
tutorial about this...on the other hand,
partimage seems just what you need...
By the way, different than the *other* one, all the settings are kept in your folder, so a simple copy of your folder (including the invisible stuff of course) should do the trick for the most part...
