All of you might want to backup your system into a boot-able ISO file which can further used to create your own Linux destro your backup of your system which can used to recover files in case your system crashes.
OS geek like me very frequently shifts from one OS to another and every time we install an an OS then we have to reinstall of all the packages and softwares. Well there is a remedy to this problem for Ubuntu[Linux] users i.e "Remastersys".
remastersys was a free and open source program for Debian, Ubuntu-based, Linux Mint or derivative software systems that can:
Create a customized Live CD/Live USB (a remaster) of Debian and its derivatives.
Back up an entire system, including user data, to an installable Live CD/DVD.
You can read further about remastersys here https://en.wikipedia.org/wiki/Remastersys
Well now it is hard to find remastersys for Ubuntu 14.04/Linux deb package
But the solution shown below works .
Go to http://filewatcher.com/
Now search "remastersys" in the search box
Download the following two packages
1. remastersys 3.0.2-1 all.deb
Click the following link remastersys 3.0.2-1.deb
2. remastersys-gui 3.0.2-1 amd64.deb (for 64 bit systems)

You can also try other versions for .rpm files if you wish, but one ststed here works well.
Now before you proceed, you need to install plymouth on your system, so open terminal and type the following command
