Patent ID: 10565062

Abstract:
The disclosed computer-implemented method for managing replication of data to a remote storage device may include (1) maintaining a first bitmap and a second bitmap storing data acknowledging persistence of target data, respectively, at source and target gateways, where the target gateway serves the remote storage device, (2) sending replication data from a computing device to the source gateway, (3) setting a bit in the first bitmap, where the set bit corresponds to the replication data sent to the source gateway, (4) receiving a first acknowledgement indicating the source gateway received the replication data, (5) copying, in response to the first acknowledgement, the bit to the second bitmap, (6) clearing, in response to the first acknowledgement, the bit in the first bitmap, and (7) receiving a second acknowledgement indicating the target gateway received the replication data. Various other methods, systems, and computer-readable media are also disclosed.
