On my laptop I am a bit more relaxed: I just copy the volume mounted on “/” to an external disk. For all data volumes I have a separate backup routine. Therefore, I also copy it to a backup file on an external disk. As I have all of my personal and project data on separate LVM volumes with dedicated backups, the root-volume is the only one which I really must take care of. Reason: I want to be able to quickly switch to my present installation in case of trouble.

On my desktop PCs with Opensuse-installations, which I use for daily work, I follow a two-fold “backup”-policy ahead of upgrades: I copy my root-volume/partition to another LVM-volume or partition, and make it bootable in parallel to the existing installation. Backup of the encrypted LVM volume mounted on “/” With some modifications you should be able to adapt it to your situation. Below I describe the steps I have taken to upgrade. At least regarding the things I was interested in. The good message is: The upgrade from leap 15.3 to 15.4 went very smoothly. The Nvidia card is also an old one – a GT 645M which cannot be run with the latest generation of Nvidia drivers. So, there are a lot of things which can go wrong. In addition we have KVM and VMware WS Pro installations. So, it hosts a variety of services you normally find on servers. Python development, as well Web-development based on LAMP. Furthermore, the laptop is used for both Machine learning, i.e.

For some of my activities I also use Blender with full OpenGL support in form of a Flatpack installation. On Leap 15.3 I did not yet apply Wayland – but I intend to switch to Wayland with Leap 15.4. I use KDE as my graphical desktop environment. Instead of Bumblebee I have used Opensuse’s Prime-Select with Leap 15.3. It is an Optimus-System – and in the past it was not always easy to switch from the integrated Intel graphics card to the dedicated Nvidia card. Its LVM volumes are fully encrypted with LUKS 2. It has a somewhat complicated configuration: I am always a bit afraid of upgrading my old laptop. (The support for Leap 15.3 ended the at the end of 2022.) But last weekend I used some time to start the long overdue upgrade of my old laptop from Opensuse Leap 15.3 to Leap 15.4. After my retirement I was overwhelmed by a lot of typical German bureaucracy.
