Garuda Linux has a setup where you can even boot into the snapshots from GRUB, but it is a little more bloated than EndeavourOS and I feel like it’s also less stable. Still definitely worth a try.

Is there a Arch with Installer that delivers this as Standart for rollbacks?

Yes, Manjaro. It will set everything up for you if you choose btrfs for the root partition. It will take snapshots before every upgrade and you will find them in a Grub submenu.

Obligatory disclaimer, Manjaro is a super-opinionated and customized Arch derivative, to the point some people don’t consider it Arch. It uses the Arch binary packages but delays and curates them into a “stable” branch which doesn’t exist on Arch. It basically requires you to stick to this stable branch, to use a LTS kernel, to install drivers through their driver manager etc.

Personally I like it because I like the idea of a rolling distro with a safety net, and it’s been working great for me over the last 4 years (daily driver for work and gaming). But it’s not everybody’s cup of tea.
