    Default Damage Control - How to back up as many setting as possible for reinstall

    Dear SuSEr's,

    I've got myself in a bind concerning my OpenSuSE 13.1 installation. Long story short - I didn't label my media properly and installed the 32-bit version when I wanted the 64-bit version. I didn't find out until I first opened up System Monitor yesterday - several hours after customizing my desktop, browser, packages, etc.

    Goal: I have already invested hours into customizing my desktop, browser, installing packages, etc and would like to keep as much of that as possible when installing the 64 bit version. (Possible?)

    Additional Info: When I installed OpenSuSE I chose BTRFS. The setup created several partitions for the install. Is there a way to only reinstall the parts needed for 64 bit operation? My Home and Root are different partitions - hopefully that will give me more options.

    You can keep home intact, just tell the installer to format the rest.
    For the packages, you can make a list:

    Code:
    rpm -qa --last

    You don't need to change any of that. Just tell the installer to import
    fstab.


    Note: it is possible to "upgrade" the system to 64 bits. The operation
    is not easy, but it is possible. If you want to try, I'll explain.

    Thank you for the response.

    You mention to tell the installer to import fstab - is that option available in the graphical installer?

    Yes.
    When it comes to Suggested Partition (which will then probably be definitely not what you want because there is no free space on the disk), go for Create partition Setup. IIRC you get then the screen Preparing Hard Disk where you go for Custom Partitioning. Somewhere on that path there is a possibility to Use Existing Partitioning.

    That should most probably give you a proposal to your liking. Check that the partition to be used for /home is the same as it was on your present system and that it is NOT to be "formatted". Swap and / should also be the same as before.

    What is also a nice feature:
    At the screen Create NEW User go for Change. The screen User settings: scheck Read User Data from Previous Installation. You can then choose which already existing users you want again. Probably All.

    Installation mode -> new installation
    Use automatic configuration -> no.
    Suggested Partitioning -> Import Partition Setup button

    And as an addition to your original question on what toi backup:
    Apart from the user data (in /home as and eventualy elsewhere), I backup /etc (not to restore blindly, but to consult system configuration when in doubt if a new install is done to the same config as before in some subjects).
