The Multiclient Backup Replication Apparatuses, Methods and Systems (“MBR”) transforms pairing request, replication data stream inputs via MBR components into pairing response, replication confirmation outputs. A replication notification for a snapshot of a backup volume at a source node is obtained. A source node named pipe for the snapshot is created. A priority for the snapshot is determined. When appropriate to send the snapshot to a replication target node, snapshot data is read from the source node named pipe and serialized into chunks Chunks associated with the snapshot and other snapshots are multiplexed into a replication data stream and sent to the replication target node via a persistent network connection. The replication data stream is received by the replication target node and chunks associated with the snapshot are deserialized. A replication target node named pipe for the snapshot is created and used to write snapshot data to a replication volume.
