Hi.
This is a little script I been working on for easy creating a kind of basic "restore point" for linux. It doesn't actually back up any files per say, it just creates a list of all packages installed in the system, backing up all repositories and the keys for it.
In the script I take use of "dpkg --clear-selections" and "apt-get dselect-upgrade" for restoring the system from the list the script makes. Make sure you know how this works before you use this script.
Also, the script will fetch all repositories in /etc/apt/sources.list and /etc/apt/sources.list.d, but will only restore it into a single sources.list file.
The script is good for restoring a crashed system, transfer a mirror installation to another computer or just to use before installing new packages you want to test. If you don't want the packages installed, just use restore and the new packages will be uninstalled again.
You can also edit the script and modify the "function userscripts()" to add your own specifik scripts you use in your system. The ones included are some that I use myself (BankID installation and fix for Asus suspend).
Script:
To use it, save the script and make it executable. Run lires -b to make a backup, and lires -r to restore previous backup. You can also specify your own name for the backup files with lires -b <file>. If you want to run the user scripts after you restored the system, use lires -rs.
Have fun! :)

Script:
Code:
#!/bin/bash
# lires v1.0
# Created by Michael Rydén 2012
# The script is free to use, copy and edit.
#
# This script makes a list of which packages are installed in the system, and also makes
# a backup of your current repositorys and their keys. These can be used to restore the
# system at a later point, or make a mirror installation on another computer.
#
# Args: -r - Restore from previous saved state
# -b - Backup current system state
# -s - Run user script
# -h - Show help
