How to make a complete backup of your PC and turn it into a live-cd

Have you ever taken your hard drive to use in another PC? Or have you missed your shows on a friend's machine? Well forget about carrying a hard drive in your backpack. Today I will tell you how convert tu current system in a live-usb/ cd easy and in just 4 steps.

Steps to follow

1.- First we are going to install all the programs that we need in our machine (or in a virtual machine): language packages, audio and video codes etc; We configure our desktop, keyboard shortcuts, launchers and everything we can think of; We uninstall the proprietary drivers (or guest aditions) to avoid problems and run on very different machines
we update

2.- Now we will install RemasterSys. This tool will create a live cd of our system. There are other similar tools but this one works very well for me.

In Ubuntu it is installed like this:

We open terminal as ROOT and paste:

wget -O - http://www.remastersys.com/ubuntu/remastersys.gpg.key | apt-key add -

Then we add one of these repositories to source.list:

gedit /etc/apt/sources.list

We paste at the end the line corresponding to our version:

deb http://www.remastersys.com/ubuntu lucid main deb http://www.remastersys.com/ubuntu maverick main deb http://www.remastersys.com/ubuntu natty main deb http: //www.remastersys .com / ubuntu oneiric main deb http://www.remastersys.com/ubuntu precise main

Then the classic ...

apt-get update && apt-get install remastersys

3.- Next we will create an .iso image, our livecd.

sudo remastersys backup myCustomLinux.iso

Even though remastersys compresses your data a lot, you may not be able or wanting to empty your “vast” collection of files. In that case, use the dist parameter:

remastersys dist myLinuxCustom.iso

A kind of official distribution will be created but with more programs and without settings or personal data.

This will take a while and will drive your processor crazy, go for a spin. When finished you will see that it has created a user folder that contains, among other things, the image to burn:

4.- Almost ready. That was the difficult part, although (as seen in the image above) the graphical interface can also be used. Now you just have to burn "MyPersonalizedLinux.iso" on a DVD. You can use brazier or k3b.

LIVE-USB: if you have already created a live-usb before you will know what to do now. Likewise, as a help you can consult the article on how to create a live-usb using Unetbootin.

5.- Finally, I recommend that you install some tools that can save you from an emergency:

foremost: to recover deleted files
the secure-delete suite: to destroy files that nobody should see
test-disk: to recover lost partitions (classic windowsero problem: the partition table is deleted and it gives the impression that "the disk was formatted").
clanav: antivirus for linux (to erase viruses from other systems)
Gparted, macchanger, aircrack, nmap, tor ... and many others.
