Why switch?
I played with the idea of switching for quite a while. Having switched my daily driver from Windows maybe 6-9 Months ago I made many mistakes in the meantime.
Good and bad
This may have led to a diminshed experience with ubuntu but all in all, I was very pleased to see that Linux works as a daily driver. Still, I was unhappy with the kind of dumbed down gnome experience.
Problems
There were errors neither I nor people I asked could fix and the snap situation on ubuntu (just the fact that they’re proprietary, nothing else).
Installation
Installing debian (and kde) was easier and harder than I expected. The download mirror I used must not have been great although its very close to my location because it took ages although my internet connections is good.
Apps
Since I switched to Linux, I toned down my app diet a lot. Installing all my apps from ubuntu was as easy as writing a short list and going through discover. Later I added flatpak which gave me a couple apps not available through discover (such as fluffychat). The last two I copied directly as appimages.
Games
I was scared that the „old kernel“ of stable debian would be a problem. As it turns out, everthing works great so far, a lot better than on ubuntu which might or might not be my fault.
Instability
Kde does have some quirks that irritate me a bit like installing timeshift (because I tried network backups which dont work with it and the native backup solution does not seem to accept my sambashare) led to a window I could only close by rebooting.
Boot time
What does feel a bit odd is the boot process. After my bios splash, it shows „welcome to grub“ and then switches to the debian start menu for 3 seconds or so, then shows some terminal stuff and then starts kde splash and then login. This feels a lot longer than ubuntu did. Its probably easy to change in some config but its also something that should be obvious.
Summary
So far I‘m incredibly happy although I ran into initramfs already probably because of timeshift which I threw out again. I might do a manual backup if nothing else works. My games dont freeze or stutter which is nice. All apps I had on ubuntu now work on debian and no snaps at all.
TL;DR: If you feel adventurous, debian and kde are a pretty awesome mix and rid you of the proprietary ubuntu snap store. It also doesnt tell you that you can get security upgrades if you subscribe to ubuntu pro. Works the same if not better.
(begging forgiveness, I haven't read the comments yet).
Regarding backups - I started with using Ubuntu and its Backup application. This application is a front end for a command line package called Duplicity. One of the things that annoyed me about the backup app was that I couldn't work out how to reschedule the scheduled backup.
Taking control of my own backup setup was the answer. Learn about bash scripting so you can create a short bit of code to handle your backups. Read up a little on duplicity, read up a little on mounting remote file shares, read up a little on setting up an ssh key for encrypting your backup.
This may be an heretical thing to say but I found ChatGPT quite useful in answering these questions (as always with anything you get from an LLM, double check it's answers against reliable sources).
Thanks for mentioning this. I‘m actually scripting quite a couple of things in bash and some in python already. I had the exact same idea.
But one reason I wrote the post was because I wanted to share my experience with debian (and ubuntu) for users that are less experienced than I am.
I even have a custom made backup script for the 50 services I run on my two ubuntu servers. It is even self cleaning.
Also tried chatgpt but so far I didnt have any luck. The code it spat out (was for screen brightness control) didnt work. But I did get it to work in the end.
