    Doomsday Prepper: spare hard drive; configuration documentation- what's needed?

    I have upgraded to 12.04 LTS from Lucid Lynx and have sorted most things out. I have a question in regard to taking measures to facilitate recovery in the event of a future hard drive crash.

    Currently I have a separate smaller hard drive that I routinely backup my /Home partition user data to. Beyond that I am wondering what steps I should take to have access to configuration data so that a replacement drive could be brought up to 'speed' with as little difficulty as possible.

    Questions:

    1. Should I go ahead and purchase another hard drive for on the shelf? Any suggestions as to it's desired features? Current main drive is 250 GB.
    2. Is there any particular utilities I can take advantage of to record my present hard drive partitioning information?
    3. Is there a way to make my backup (archive) drive bootable or should I just rely on a Live CD?
    4. What is the most efficient way to collect information on downloaded/installed apps (those taken thru Synaptic Package Mgr for instance) and upgrades to establish a listing
    for future reference?

    So really what is needed is a checklist of some sort that highlights all software presently installed & my present hardware configuration.

    Any suggestions are welcome,

    Ed

    I use rsync and copy primarily /home as that has user settings, /etc and maybe a few other things from the system. I assume I will just do a new clean install and restore my /home. But my /home has nothing in it other than user settings as all my data is on other drives.

    I also run bootinfoscript as part of my rsync which documents booting and partitions. And I export a new list of installed applications.

    I started here which is a simple rsync script. Then added to it.

    Sample rsync file, use a text editor and paste into a file & name it mybackup.sh

    Oldfred's list of stuff to backup May 2011:

    #I include these also:
    cp /etc/apt/sources.list ~/sources.list.backup
    apt-key exportall > ~/repositories.key
    #Various hardware listings/configurations
    dpkg --get-selections > ubuntu-files
    bash ~/Documents/LinuxDocs/CurrentSys/bootinfoscript.sh
    lshw -html > ~/hardware_info.html
    udevadm info --export-db > file.txt
    dmidecode > bios.txt
    If I manually edit some system file like grub or settings in /etc, I try to remember to copy to a folder in /home to save those settings as part of normal backup.

    You can exclude some data as it is not important like caches.

    I follow this logic, but have a working copy of Ubuntu on every drive and every drive is configured to completely boot without any other. But data which may give mount errors is on various drives.

    I used to use a .bat file in Windows to copy files from Windows to a single partition. Windows used to scatter my data files all over, even with My Documents. Many apps wanted their own place to store data. Then I would easily write data from that backup partition to DVDs as archived backup. I now do the same with rsync.

    rsync is just a smart copy program. Very powerful & efficient, but with power comes complexity. It can run locally or over network, or even Internet. Biggest issue I had was what parameters to use, so I just copied an good example. If you look at man rsync you will get overwhelmed with all the copy parameters.
