COMPUTER PROGRAM PRODUCT, SYSTEM AND METHOD FOR REPLICATING OBJECTS FROM REPLICATION SOURCE STORAGE TO REPLICATION TARGET STORAGE (REPLICATION OF DATA OBJECTS FROM REPLICATION SOURCE SERVER TO REPLICATION TARGET SERVER)

摘要

PROBLEM TO BE SOLVED: To replicate data objects from a replication source storage to a replication target storage with deduplication.;SOLUTION: A replication source list 30 of objects at a replication source server 4a to replicate to a replication target server 4b is built. A replication target list 32 of objects at the replication target server 4b is obtained, and a replication list 36 is built indicating objects on the replication source list 30 not included on the replication target list 32. For each object in the replication list 36, data for the object not yet at a replication target storage 8b and metadata on the object are sent to the replication target server 4b. An entry for the object is added to a replication database 8a of the replication source server 4a.;COPYRIGHT: (C)2015,JPO&INPIT
