As VictorBrand explained: you use btrfs for the / partition and ext4 for the / home partition.

So you can take a snapshot of / and a backup with rsync or grsync of your / home.
Thanks tintin
This gives me hope.
So, I should make a fresh install, manual partition only Root as BTRFS?
(If there is another way simpler it's OK. I don't care about data on home partition as I have backup)
UPDATE:
Searching I found something like install btrfs-tools then,  btrfs-convert /dev/xxx

I should boot from the live USB I think. Right?
OK to try? Any special hints or precautions? Of course I prefer to "convert" rather than reinstalling and setting up everything allover again.
I'll appreciate commands in sequence (honestly to copy/paste)
Perhaps we should make a separate thread "How-to Convert from EXT4 to BTRFS"

Thanks

Yes, you have to boot from an install media.

Code: [Select]
# btrfs-convert /dev/partition
and then adapt / etc / fstab.
chroot into the system and rebuild your bootloaders menu list (see Install from existing Linux). If converting a root filesystem, while still chrooted run mkinitcpio -p linux to regenerate the initramfs or the system will not successfully boot.

When ext4 replaced ext3 few times delayed allocation caused zero files.
It was fixed but I didn't feel safe with ext4 and it had no interesting options.
As beginner with Ubuntu I often had system broken and it was more easy to reinstall than fix things.
So I used fsarchiver to backup working partitions. It is fast and has good compression.
When BTRFS matured (and also my knowledge of Linux) I started using it.
Once I had an undeletable file because after sudden reboot. But I use snapshots and backup configs so this wasn’t a problem.
Tried to use zfs but it didn’t work with full encryption.

What are your experiences?

My experience with ext4 for over 7 years.
Whatever I do with it, it works flawlessly.
Ext4 is the only system I like.

I use f2fs for over 2 years i think and it's bullet proof. Had power outages and it did not broke. It may need occasionally to be defragged. f2fs is much faster than ext4 and updates literally can  be installed in a blink of an eye.

i tried f2fs without much success.  buttery farts file system trashed a hdd some 9 or 10 years ago and i will NEVER give it another opportunity i don't care what anyone says.

Ext4 is reliable.  has never trashed a hdd.  is movable from drive to drive.  I have previously upgraded from hdd to ssd and then to nvme and just copied the partitions over (legacy boot)  chrooted in, changed the uuids, edited fstab, reinstalled grub and was off to the races on reboot without a hitch.

Used to like reiser.  also used mandriva circa 2003 with that reiser. No one really seemed to do much else with reiser after he went to prison.  There was a resiser4 but how long ago was that?

Using ext4, even though I'd really, really, really prefer to use XFS. I just stopped trusting it because I lost some data from a brown out because of it's lack of function at the time. Plus can't shrink it yet so, still waiting. Which will never probably happen, so ext4 even on ssd works stably, even in the face of power loss and orphaned inodes.

If that helps any.
