This chapter explains the operation of the replication function.
Using the advanced copy (OPC or EC) function of an ETERNUS disk array unit, the replication function performs high-speed replication between volumes, regardless of the volume capacities.
Snapshot replication is the term used for the replication function that uses the One Point Copy (OPC) or Remote One Point Copy (ROPC) function of a Fujitsu ETERNUS disk array unit.
Synchronized Replication is where either the Equivalent Copy (EC) or Remote Equivalent Copy (REC) functions are used.
The replication function creates copies so that the information at a certain point in time can be used for different purposes. It can be used either independently of or in combination with the backup function.
