Data replication includes generating replication data that is part of a replicated file system to be sent over a communication channel to a destination replication device; adding additional verification information to at least a portion of the replication data to prevent data corruption; and sending the replication data and the additional verification information over the communication channel to the destination replication device. The replication data with additional verification information is sent over the communication channel using a reliable protocol that allows the replication data to be verified by the reliable protocol at the destination replication device. The reliable protocol is a protocol capable of detecting most but not all data corruption introduced by the communication channel. The additional verification information includes information for verifying that replication data sent using the reliable protocol does not include data corruption that was introduced by the communication channel and undetected by the reliable protocol.
