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.
This and this are useful but I guess solution to my problem is simpler than this.
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 grub and etc/fstab? Please help this newbie to understand this.
