Systemback Usage in Ubuntu Desktop
Once installed, Launch Systemback either from Menu or Unity launcher.
The default interface should look like below.
As you see in the above screenshot, there are five sections namely,
Restored points - List of available restore points
Highly restore points
Point operations - Create, hightlight, rename or delete restore points
Storage directory - The location of saved restore points
Function menu - This menu contains the main options such as System copy, restore, install, live system create, system repair, system upgrade, exclude, include, Schedule, and Settings etc.
Creating System Restore Points
At first launch, there is no restore points. So, let us create our first restore point. You can create any number of restore points either manually or automatically.
To do so, click Create New button under Point operations section.

The newly created restore points will be stored under /home directory by default. You can change this location from Storage directory section. Make sure you have enough free space in the storage directory (i.e /home directory).
