How can I make a backup of the system and then restore it, in case of serious damage or failure? This is possible after a failed experiment.

You can use TimeShift for creates system restore point.
TimeShift for Linux is a application that provides functionality similar to the System Restore feature in Windows and the Time Machine tool in Mac OS. TimeShift protects your system by taking incremental snapshots of the file system at regular intervals. These snapshots can be restored later to bring your system to the exact state it was in at the time when the snapshot was taken.
TimeShift is designed to protect system files and settings. User data such as documents, pictures and music are excluded by default.
Install:
sudo apt-add-repository ppa:teejee2008/ppa
sudo apt-get update
sudo apt-get install timeshift
Typically, for use doesn't require any additional settings, just click the Backup button for create snapshot.
For restore select a backup from the list and click the Restore button on the toolbar. After, select the system partition from the Restore Window that is displayed. Click the Restore button to continue and start the restore process.
You can be enabled for taking automatic snapshots of the system at regular intervals. The backup levels can be selected from the Settings window.
If you can't get into the graphics mode (eg after a failed installation of video driver), you have to use Live USB with elementary OS or Ubuntu. After booting into the live system, run the commands in terminal to install timeshift and follow the general instructions for restore.
