Timeshift makes a snapshot files and saves your whole system and you can then go back in time. You can set it to take these at pre-set times. You can have several Timeshift snapshots files so you can choose where to go back in time when you restore. You should now make your first Timeshift to save your whole system.
You can find Timeshift on your panel 
Run Timeshift Ignore the first page click NEXT.

I clicked on NEXT which sets out when you want to make a Timeshift automatically then I clicked on Finish to get the Timeshift main page. I clicked on Create to make my first Timeshift that to obtain the Timeshift Main Page here.
You can also use a USB formatted as Ext 4 if you want to Timeshift on a USB. You can also use Discs.

Restoring Timeshift can be done from the Timeshift page. Search for Timeshift then run and select the Timeshift snapshot you want to restore then click on NEXT. Then choose where you want to restore on the partitions displayed in the pop-up menu then click NEXT.
After restoration you should CREATE again in case you have a problem before the next auto Timeshift snapshot is taken.
