Abstract
A computer program product, system, and method for generating coded fragments comprises receiving, at a primary data protection appliance (DPA), an I/O write for a user volume; determining a distributed consistency group (DCG) associated with the user volume, the DCG having a plurality of replica copies; determining one or more secondary DPAs assigned to one or more of the replica copies; sending the I/O write from the primary DPA to each of the secondary DPAs; and applying, at each of the secondary DPAs, the I/O write to at least one of the replica copies assigned to the secondary DPA.
