1. Asynchronous Replication (as oppose to Synchronous Replication) is when the data has been written to the primary storage site, new writes to that site can be accepted, without having to wait for the secondary (remote) storage site to also finish its writes.

Related Terms: Asynchronous, Replication, Data Protection/Recovery Strategy - Category.

Note: Asynchronous Replication does not have the latency impact that synchronous replication does, but has the disadvantage of incurring data loss, should the primary site fail before the data has been written to the secondary site.
