6 PS Series Asynchronous Replication Best Practices and Sizing Guide | BP1012
Asynchronous replication addresses varying needs using powerful features and configuration flexibility:
 Multiple recovery points are efficiently stored.
 Per-volume replication schedules permit varying service levels.
 You can fast failback to the primary site by synchronizing only the data that has changed while the
secondary site was in use.
 One-way, reciprocal, one-to-many, or many-to-one replication paths are possible.
 Thin replicas provide space efficiency.
