Essa ferramenta existe, é chamada Timeshift . O artigo vinculado é sobre o Ubuntu, mas funciona para várias distros.
Wouldn’t it be nice to be able to try a new version of Ubuntu while knowing you can return to the previous version if you don’t like it? We’ll show you a tool that allows you to take a snapshot of your system at any time.
TimeShift is a free tool that is similar to the System Restore feature in Windows. It allows you to initially take a snapshot of your system and then to take incremental snapshots at regular intervals. TimeShift protects only system files and settings, not user files such as documents, pictures, and music. You can use a tool like Back In Time to backup your user files.
