I don't like to talk about Apple’s and Windows,
I Speak LINUX so it’s OK
I began my quest to bring my Linux with me wherever I went, I did some searching online and asked several friends in the Ubuntu community, I was pointed the direction of Remastersys. What it does is backs up your current version of Linux on your P.C., with all your files as well. Meaning when you have all the apps you need installed you will be able to put it on something as small as a USB drive.......or wait, your phone!
That's right, if you have an android device you can get an sd card that's bigger than a 4gb (the room is much easier with this size and bigger). You can then format the sd card to a FAT32 and use Remastersys and have a portable Linux distro wherever you go on your smartphone, pretty handy ill say.Unless you are one of the few who don't carry their phone with you wherever you go. But I doubt you're a Linux user if that's the case, plus reading this far into the post.
In the photo in the start of this post is a link to clonezilla, it's another option which is fine to. With personal experiences if just found out this way to work for me. But I always figure the way people learn it the first time, as long as it's not too much harder than another way, is the way they will continue to do it.
Well here is a quick guide on how to install Remastersys on your Linux P.C., I'm using Ubuntu 12.04 so yours could be slightly different.
First open up your terminal and type;
Wget -0 - http://www.remastersys.com/Remastersys.gpg.key. | apt-key add. -
sudo gedit /etc/apt/sources.list
When that opens up add the following lines and click save;
deb http://www.remastersys.com/ubuntu precise main
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
Reopen terminal and type;
sudo apt-get update
Then open up the synaptic package manager and search for;
Click and have it installed and press apply.
Now you should have Remastersys installed in order to make a back up of your current Linux distro!
