Best way to backup all settings, list of installed packages, tweaks, etc?
I am very happy with Ubuntu, the way my friend set up all basic applications like libreoffice and web browser, Ubuntu rolls smoother than expected.
I am ex-windows user, just worried to back to everything with all softwares-n-settings preserved so that it can be re-installed if anything goes wrong.
Is there any way I can back-up everything like re-mountable ISO?
Please suggest the best method to back-up whole set-up for exactly same configuration so that I do not depend on my friend who set it for me.
