Abstract
An apparatus is configured to initiate a first replication session to replicate data of a first consistency group in a first storage system to a second consistency group in a second storage system, to create an additional consistency group linked to the second consistency group in the second storage system, and to initiate a second replication session to replicate data of the additional consistency group to another consistency group in a third storage system. The additional consistency group linked to the second consistency group in some embodiments is periodically updated against the second consistency group. For example, in one or more embodiments the second consistency group is updated based at least in part on an active snapshot set of the first replication session, and the additional consistency group is updated based at least in part on the second consistency group.
