Replication in AdvancedCopy Manager uses the same advanced copy functions (OPC and EC) of ETERNUS to perform high-speed replication. It can be used explicitly as a replication mechanism or as an online backup function with history.
For the purpose of this overview, replication is defined as copying that is intended for concurrent use by other applications. The destination volume in a replication remains accessible, unlike destination volumes in backup which are typically unmounted.
Replication is not limited to within a single Storage Server or one of ETERNUS disk storage systems. Using REC, the replication can also be performed across different ETERNUS disk storage systems regardless of geographical locations.
Features of replication using AdvancedCopy Manager
With the AdvancedCopy Manager replication function, replication can be configured in two directional modes:
Uni-directional: copying can only be performed from the source volume to the destination volume
Bi-directional: copying can be performed in either direction between the two volumes
If the copy source and copy destination volumes are both in the same ETERNUS and hosted by the same Storage Server, data can be copied in real-time.
High-speed replication can be executed at the following databases without interrupting operations that are in progress:
Symfoware Server (Fujitsu)
Oracle Database (Oracle Corporation)
SQL Server (Microsoft Corporation)
Exchange Server (Microsoft Corporation)
DB2 (International Business Machines Corporation)
