As you may know, TimeShift is a tool that allows the users to do system restores to a certain time. It is an open-source restore tool, similar to Microsoft’s System Restore and Apple’s Time Machine, based on rsync and hardlinks, that creates incremental snapshots for the file system. It can be used as LiveCD or as an application, for the Ubuntu and derivated systems.
The latest version available is Timeshift 18.9.1, which brings fixes.
