System and method for highly reliable data replication

A data replication method comprising:

• generating replication data, wherein the replication data corresponds to at least a part of file system data to be replicated on a destination replication device;
• generating additional verification information based at least in part on at least a portion of the replication data;
• including in a first container the replication data and the additional verification information;
• including the first container in a second container associated with a reliable protocol;
• and
• sending the second container including the first container over a communication channel to the destination replication device, wherein the destination replication device is configured to verify the replication data, upon receipt, at least in part by determining whether at least a portion of the second container can be verified using the reliable protocol and in the event that the second container is verified by the reliable protocol, then checking the additional verification information included in the first container to further verify that the replication data does not include data corruption that was introduced by the communication channel and undetected by the reliable protocol, wherein a verification associated with the additional verification information is stronger than a verification associated with the reliable protocol.

A computer program product for data replication, the computer program product being embodied in a non-transitory computer readable storage medium and comprising computer instructions for:

• generating replication data, wherein the replication data corresponds to at least a part of file system data to be replicated on a destination replication device;
• generating additional verification information based at least in part on at least a portion of the replication data;
• including in a first container the replication data and the additional verification information;
• including the first container in a second container associated with a reliable protocol;
• and
• sending the second container including the first container over a communication channel to the destination replication device, wherein the destination replication device is configured to verify the replication data, upon receipt, at least in part by determining whether at least a portion of the second container can be verified using the reliable protocol and in the event that the second container is verified by the reliable protocol, then checking the additional verification information included in the first container to further verify that the replication data does not include data corruption that was introduced by the communication channel and undetected by the reliable protocol, wherein a verification associated with the additional verification information is stronger than a verification associated with the reliable protocol.
