Asynchronous replication

In the asynchronous mode of replication, the application updates are immediately reflected at the primary site and sent to the secondary site as soon as possible. The updates are stored in the Replicator Log until they are sent to the secondary site. This allows asynchronous replication to deal with temporary network or secondary host failures without affecting the performance of the application.

Asynchronous replication mode is most effective in application environments where it is not acceptable for the application performance to be impacted, only a minimal data loss can be tolerated, or the application has a high rate of updates.
