The record of all changes made to the application Consistency Group, maintained by the RealTime server as a result of the data capture process. When data capture is initiated, that is, when the timeline is started, the appliance begins capturing all writes made to the Consistency Group via the virtual TimeSafe volumes. This record of write transactions is saved in the timeline and is what the system uses when it creates a TimeImage or performs a restore. Thus, the timeline represents the window during which the RealTime server has been protecting the targeted application’s Consistency Group, as well as the repository from which an historical image of the Consistency Group can be recreated.
