Abstract: Systems and methods are described herein for a service that backs-up and stores events received at an event bus, in order to replay those backed-up events at a later time. In one example, a request to replay an event processed by an event bus may be received, for example, by a service. The event bus may process events by directing individual events to a target to perform an operation on the data. Individual event may include data and metadata indicating attributes of the data. A data object, corresponding to the event may be obtained from an event archive, which stores multiple events organized into a number of data objects according to attributes of the events. An event may be extracted from the data object and sent to the event bus to be reprocessed by the event bus and directed to the target to perform the operation on the data.
