What are the Alternatives For RemasterSys?!
How to make full copy of Ubuntu (12.04.1), with ability to "unpack" it from Windows, to my another flash card (to have two copy of my Ubuntu OS).

This will create an archive file in your home directory containing the entire system and all your personal data.
If you're only looking for a backup, it might be sufficient to back up your home directory though, and not the entire system. After all, you can always reinstall the OS and software, but personal data is a lot worse to lose.
