Snapshot replication refers to replications that use the One Point Copy (OPC) function of ETERNUS disk storage systems. This section describes the procedures for performing OPC, QuickOPC and SnapOPC using the AdvancedCopy Manager GUI Client.
For details of each copy type, refer to the "AdvancedCopy Manager Overview" and "AdvancedCopy Manager Operator's Guide".
Replication can be performed by volume or by group
Select a Replication Group or Volume Pairs from the site view and right-click to invoke the context menu.
Click [Start OPC] to invoke the [Start OPC] dialog box and select from a range of OPC options.
