I have the following MAJOR “directories� or “folders� in my Knoppix HD install:

bin
boot
cdaudio
cdrom
dev
dvd
etc
floppy
home
initrd
lib
lost+found
mnt
none
opt
proc
root
sbin
sys
tmp
usr
var
I would like to perform a total apt-get update, and apt-get upgrade. Problem is I don't want to loose any of the formatting and settings I have done up to now.

Question – what of the above file folders should I backup to another drive before the upgrade? Can I then “copy� these folders back into the “upgraded� Knoppix without having to go through all my formatting and settings again? Is there a “simple� way to do this?

Rather than using apt-get, should I use dpkg instead

Thanks
