Policy-based replication: Asynchronous

Policy-based replication uses volume groups and replication policies to automatically deploy and manage replication. Policy-based replication significantly simplifies configuring, managing, and monitoring replication between two systems.

With policy-based replication, you can replicate data between systems with minimal management, significantly higher throughput and reduced latency compared to the remote-copy function. A replication policy has following properties:

A replication policy can be assigned to one or more volume groups.
Replication policies cannot be changed after they are created. If changes are required, a new policy can be created and assigned to the associated volume group.
Each system supports up to a maximum of 32 replication policies.
