For years we had the request to provide rollbacks for YaST and zypper but things never got far due to various technical problems. With the rise of btrfs snapshots we finally saw the possibility for a usable solution. The basic idea is to create a snapshot before and after running YaST or zypper, compare the two snapshots and finally provide a tool to revert the differences between the two snapshots. That was the birth of snapper. Soon the idea was extended to create hourly snapshots as a backup system against general user mistakes.
