SYSTEM AND METHOD FOR HIGHLY RELIABLE DATA REPLICATION
First Claim
1. A reliable replication system comprising:
- a processor configured to;
include in a first container replication data and additional verification information based at least in part on the replication data;
include the first container in a second container associated with a reliable protocol; and
an interface coupled to the processor, configured to send the second container including the first container over a communication channel to a 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 is communication channel and undetected by the reliable protocol.

Abstract
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.
