Shelly and donna are discussing system restore. shelly says when the system restore program creates and saves a copy of your computer's configuration, this copy is called the restore copy. donna says it's called the restore point. who is correct?

Donna says correct. In a System Restore, the representation of a stored state of the system files in your computer is called restore point. It is use to restore the computer’s system files to an earlier point of time. The user may manually create the restore point, rollback to a restore point, or change the system restore configuration.  

What are the choices?
