snapper

Snapper is a filesystem snapshot tool commonly used on Linux distributions like openSUSE Tumbleweed, particularly with the Btrfs filesystem. It creates automatic snapshots before system updates, allowing users to easily roll back changes if an update causes problems. This makes updates safer and less risky compared to the typical Windows update experience, where recovery can be more complex. Snapper integrates deeply with the system, providing a safety net that many Windows users have to set up manually. The tool is often praised for making update failures cheap to undo, turning what could be a gamble into a reversible action.
