Abstract
Embodiments of the present disclosure provide a method and device for data duplication cutover. The method includes initiating duplication of initial data from a source device to a destination device, wherein the initial data are data of a file system stored on the source device upon the initiating. The method further includes, in response to completing the duplication of the initial data, updating a session associated with the file system. Furthermore, the method includes, after updating the session, triggering the source device and the destination device into a data unavailable state to perform duplication of delta data from the source device to the destination device, wherein the delta data are data of the file system changed during duplication of the initial data. Utilization of the cutover mechanism proposed in the present disclosure enables effective reduction of data unavailable period of time.
