METHOD AND SYSTEM FOR OPTIMIZING DATA REPLICATION FOR LARGE SCALE ARCHIVES

摘要

A method and system for processing query requests, including receiving, at a secondary site, a query request from a client and executing the query request to obtain an archive replica package (ARP). The method further includes making a determination that a record associated with the ARP is not stored at the secondary site and based on the determination, transmitting a request to a primary site. The method further includes, in response to the request to the primary site, receiving an archive package and a record where the archive package is associated with the record, and providing the first record to the client.
