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.

That sounds like a job for btrfs snapshots, they're provided by default in openSUSE
Cries in ext4
You can try doing an in-place conversion, here's a guide and the official documentation, remember to BACKUP and TEST your BACKUP at least twice, if things don't go well, you'll be able to fall back.
If you want to avoid all the setup headache, just reinstall with btrfs by default (I suggest Fedora Silverblue or openSUSE Tumbleweed for that) of course you'll still have to backup, just your data though, to be restored on the new system
Second suggestion for SilverBlue today. Maybe I will try it out once I have enough time on hand to backup my system and then restore.
I've been loving it honestly, I used to mess up my systems pretty often in a way that upgrading to new releases had to be done from the command line because of random repositories I added, so things felt unstable.
Immutable systems on the other hand are dumbass (me) proof and I can still do what I used to do with those repos in safe environments or Flatpak now that it has become so ubiquitous for packaging.
Immutability is not a must, even though I really like the philosophy, in fact, if you're comfortable with what you have, you might be fine just converting over your current OS to btrfs.
Good luck, whichever option you try!
Thanks for informing. Will be definitely trying it.
