This is possible by creating a point of recoverythat capture the state of the system at any particular point in time. These points are created automatically once per day or upon the occurrence of certain system events. Also it is possible to create them manually. This can be done in the following way: "Master recovery system" → "Create point restore" → "Description of the control point" → "Create".
To save them you'll need at least 300 MB of free hard disk space. They are stored until then, until you filled the disk space that is reserved for the recovery system. Decreasing space of the old points are deleted to make room for the new.
