This question already has an answer here:
I want to backup all my installed applications so that I can use them in fresh installation of Ubuntu (12.04 as of now) later.
APTonCD only picks up .deb ( at
/var/cache/apt/archives) but I have installed packages by downloading from the internet. What I want to backup all my applications and configurations so that I do not have to go through the hurdle again.
Why can't I backup all everything within the root (
/) and then when ubuntu is installed fresh just copy all the files to the new
/ and then do
sudo apt-get update and update
etc/fstab? Please help this newbie to understand this.
