Remastersys was an old backup program that converted a running Ubuntu or Debian system into an installer disk with the same packages as the 'master' installed, or into a live backup of the environment you were working on. It was dead simple (basically entirely automated as long as it was a supported system with enough space), and very useful for remastering your own disks. And the person who developed it had some clashes of personality with persons unknown, and, unfortunately, stopped developing it. Black Lab Linux's System Imager is a fork of this, but let's just say the selling price, and what I'm willing to pay don't match.

So, this is what I need:

  • I need to be able to back up a running Linux system with all the packages on it
  • I need to generate an ISO from this which I can then mount on live USB
  • It needs to be relatively simple - I don't want to jump through a bunch of hoops to get this to work
  • GUI preferred, though if it's curses-based and will run me through dialogues to back up a CLI-only system, it's super-cool
  • Works on Ubuntu and Debian at least, though if it works on Fedora and RHEL, I'd be overjoyed

Options I'd like to have:

  • Pick between backup mode - with my /home copied over to the live CD too or to generate a 'fresh' system for install with my packages
  • supports Btrfs filesystems

See Pinguy Builder:

The script creates a livecd of the installed system and works with *buntu. You can either make a distributable livecd or a backup of your system. Version 3.* works with *buntu systems 14.04 (May also work with 14.10. If not use version 4.*)

Version 4.* works with *buntu systems 15.04+ (15.10 Beta1 is missing xresprobe)

xresprobe can be downloaded from here: https://launchpad.net/ubuntu/+source/xresprobe

Once xresprobe is installed in 15.10 Pinguy Builder will work/install.
