US Patent 11360688 Cascading snapshot creation in a native replication 3-site configuration

In one aspect a data replication process in a storage system includes creating, at a first target site, an empty container in a storage system. The empty container matches a container at a source site in response to initiation of an asynchronous data replication process. An aspect also includes transmitting a command to a second target site to create a container at the second target site. The first target site performs the asynchronous data replication process, which includes scanning the data upon receipt from the source site for a first target replication cycle and transmitting the scanned data to the container at the second target site for a second target replication cycle.
