Timeshift works only with BTRFS subvolumes, thus, if you wanna have backups (snapshots), you have to have subvolumes and not install in the root of a BTRFS filesystem 😔.
That’s only to backup/rollback the root though, right? If one’s looking to backup - say - their home dir, they can just recreate the home as a subvolume without reinstalling the system. Or am I mistaken?
If you want to you can just create a new subvolume, mount it temporarily and move all your files from root to there. Then you need to figure out how to make the new subvolume your root directory upon boot and you are done.
Snapper also uses btrfs subvolumes to create snapshots, so if you did create them during your installation process, nothing to worry about.
I don’t remember if there is a way to create them after the installation, neither if it’s a tough process tho. I used to simply reinstall when I messed up with the subvolumes.

You can definitely do this with a few commands.
Thank you for sharing your knowledge.

Oh okey so if I have Snapper already, nothing I need to worry about?

sudo btrfs subvolumes create /path/to/subvolumeIf you don’t configure anything, root will already be a subvolume.
If you wanna make a used directory a subvolume, you have to move the contents first, and move them back after creation.
The only thing that takes time here is the move
