Abstract

Event detection logic detects events which may be associated with a change in risk of potential data loss in a data replication system. Mode selection logic is responsive to detection of such an event to select a data replication mode such as a synchronous data replication mode, for example, as a function of a detected event for initiation of a switch to the selected mode. In one embodiment, upon detecting that the event which lead to initiation of a switch to the synchronous mode has been completed or otherwise resolved, the mode selection logic can initiation of a switch of the data replication mode of multi-mode data replication logic back to an asynchronous mode so that data is replicated in the asynchronous data replication mode. Other features and aspects may be realized, depending upon the particular application.
