Abstract
Implementations described and claimed herein provide systems and methods for resumable replication. In one implementation, an interruption in a transfer between a source and a target is identified. The transfer includes a send stream generated by the source and configured for receipt by the target. The send stream includes one or more snapshots of the source. A receive checkpoint generated by the target is received at the source. The receive checkpoint indicates data successfully received into the target during the transfer prior to the interruption. The transfer is resumed based on the received checkpoint. The resumed transfer skips any of the one or more snapshots and all data in a resumable snapshot already existing on the target. A complete transfer from the source to the target is verified using a chain of custody.
