SUSE Certified Engineer - Using Snapper Lab
In this hands-on lab, you'll be getting familiar with the snapper command and the mechanisms that support it. You'll setup snapper with a configuration for the root filesystem, verify the configuration and make an important setting change. You'll then work with snapshots, viewing the differences in various ways between snapshots and the current state and then work with pre and post snapshots to undo and redo changes, such as the installation of a software package.
