Abstract: A method and system is disclosed to maintain data consistency over an internet small computer system interface (iSCSI) network, for disaster recovery and remote data replication purposes. Data consistency and replication is maintained between primary and secondary sites geographically distant from each other. According to the method, a primary journal volume logs all changes (data writes) made to a primary volume, transmits the changes based on a preconfigured policy to a secondary journal volume, and thereafter merges the changes stored in the secondary journal volume with a secondary volume. Changes in the journal volumes are ordered in point-in-time (PiT) frames and transmitted using a vendor specific SCSI command utilizing the iSCSI protocol.

Abstract: An apparatus and method for providing a storage system snapshot copy while allowing the execution of I/O operations without latency. A host request to write a data chunk to a production volume is served by writing the new data chunk to a journal, and upon writing, a response message is sent to the host signaling the end of the execution. The method thereafter performs off-line copying of the original data chunk from a production volume to a snapshot volume, and writes the new data chunk to the production volume.
