Abstract

A method and system of providing cascaded replication is disclosed. According to one embodiment a method is provided in which data to be written to a data volume of a first node is replicated to a data volume of a second node and data to be written to the data volume of the second node is replicated to a data volume of a third node where at least one of the replication operations includes asynchronous data replication.
