Generating Initial Copy in Replication Initialization

TL;DR: In this article, a method, system and program storage device for asynchronously transmitting one or more incremental database updates from a primary volume at the primary site to a remote volume at a remote site, where the primary sites and the remote sites interconnected by at least one communication link is provided.

Abstract: Provided are a method, system, and program for determining changes made to a source file to transmit to a target location providing a mirror copy of the source file. An operation to modify a source file at a source location is detected, wherein a target file at a target location includes a copy of a version of the source file. A base copy of the source file is created. The operation to modify the source file after creating the base copy is executed. Differences are determined between the source file and the base copy of the file. The determined differences are transmitted to the target location, wherein an aggregation of the target file and the transmitted determined differences comprises the modified source file.

TL;DR: In this article, a synchronization relationship between the source node and the target node is established and maintained for disaster recovery, real-time backup and failover, thereby ensuring that data on the source nodes is fully protected at an off-site location or on another server or VM, for example, at another data center, a different building or elsewhere in the cloud.

TL;DR: In this article, a copy source storage controller received write data added with a time and issued from a host computer transferred the write data with the time to a copy destination storage controller.
