Graphical user interface timeline graph for navigating events of a backup job. In one example embodiment, a non-transitory computer-readable medium stores a program that causes a processor to generate and present a graphical user interface (GUI) timeline graph for navigating events of a backup job. The GUI timeline graph includes a first axis representing time periods over which events of a backup job took place, a second axis representing a data size associated with each of the events of the backup job, and objects positioned along the first axis and the second axis. Each of the objects corresponds to one of the events of the backup job. A width along the first axis of each of the objects represents the time period over which the corresponding event took place. A length along the second axis of each of the objects represents the data size associated with the corresponding event.
