Pinguy Builder faz isso.
The Pinguy Builder will create a installable ISO of your current system. You can then burn that ISO to a USB using something like Unetbootin or just burn the ISO directly to a DVD. The DVD/USB can then be booted from a PC.
Depending on what option you choose determines what type of ISO gets created. If you pick “Dist”, this will backup the whole system but exclude your home folder and any personal info.
If you pick “Backup”, this will backup the system and will include you home folder (so make sure it isn’t to big).
Both options can run as a live session. “Dist” mode has no password to login. “Backup” mode uses the user name and password used to create the ISO.
Você pode baixá-lo do sourceforge: Pinguy OS ISO
E instale-o com
sudo dpkg -i pinguybuilder_4.3-8_all-beta.deb
Após a instalação, você pode usá-lo na linha de comando com
sudo PinguyBuilder backup|clean|dist [cdfs|iso] [filename.iso]
Ou com a GUI, que possui botões para concluir todas as ações disponíveis.
