Abstract

Systems and methods are provided for durable asynchronous replication in a distributed storage system. A storage system may commit a transaction comprising saving a data object to a persistent object storage location and saving a replication marker to a first persistent storage directory for pending replication tasks, wherein the replication marker comprises replication data for replicating the data object to a remote storage system, and wherein the first persistent storage directory comprises a replication queue; determine, based on a presence of the replication marker in the first persistent storage directory, to dequeue the replication marker from the replication queue; move the replication marker to a second persistent storage directory for in-process replication tasks; attempt replication of the data object to the remote storage system; and move the replication marker to a third persistent storage directory.
