    $sudo remastersys backup	

    OR $sudo remastersys backup Ubuntu-14.04-64bit-lampnode.backup.iso

    The ISO would be created stored in ~/remastersys.

    To make a distributable iso with your personal data

    $sudo remastersys dist

    It will create an iso image called customdist.iso in the /home/remastersys directory. The dist option makes that your personal folder (e.g. “/home/robert”) will not be included in the iso image.

    After you`ve burnt the iso image onto a CD/DVD, you can run:

    $sudo remastersys clean

    It will remove all temporary file created during the iso generation as well as the /home/remastersys directory.


    • There`s a 4GB size limit of what can be backed up and created into an ISO image of your computer.
    • DO NOT install the driver for Nvidia graphics card. You need to retain The default graphics driver.
