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.

The disclosed computer-implemented method for monitoring data synchronization progress in a multi-hop data recovery system may include (i) calculating a number of data blocks to be synchronized, (ii) setting each element of a synchronization data structure to dirty, (iii) determining a dirty bytes counter, (iv) transmitting a portion of the data blocks to be synchronized, (v) receiving an acknowledgement corresponding to the transmitted portion of the data blocks, (vi) setting a set of elements within the synchronization data structure corresponding to the transmitted portion of the data blocks to clean, (vii) determining a pending dirty bytes counter that indicates a current number of elements within the synchronization data structure that are set to dirty, and (viii) transmitting the dirty bytes counter and the pending dirty bytes counter. Various other methods, systems, and computer-readable media are also disclosed.
