From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Also, once your install is in a state you like, create a backup with CloneZilla.
Nah. This is old school thought. Use an immutable distro if this is your concern, and keep all your files on a NAS, or something else that can replay your files. Local images of your entire filesystem isn't needed anymore.
Neither an immutable distro nor a NAS is a replacement for backups.
Some people are lucky enough to never learn that backups are vital. Good luck to you in the future!
They are two different things.
A Clone of an OS install is not needed anymore, for a jillion reasons.
Personal files do not relate to that.
Perhaps you don't understand how these are intended to work?
If my SSD decides to suddenly quit, I can get back all my personal files and configs, plus all the software I had installed with all configurations, configured repositories, user rights and group memberships, GUI customizations, system-wide fonts, .desktop-files, root .bashrc, self-compiled software, etc. etc. by popping in a new SSD and
dding my full disk image backup to it with one terminal command.I fail to see how that is not a nice thing to have even today, or how I would get back to the previous state just as fast without it.
Heyha ! Read about dd on makeuseof after reading your post, to see how it works.
Restoring from an image seems exactly what I was looking for as a full backup restore.
However this kind of 1 command backup isn't going to work on databases (mariadb, mysql...). How should I procede with my home directory where all my containers live and most of them having running databases?
Does it work with logical volumes? Is it possible to copy evrything except /home of the logical volumes?
For special use cases like that, dd isn't the right tool.
Okay, thank you :)) too bad it looked liked a simple and elegant way...
