Abstract
Computer-implemented methods and systems for replication of data between mirrored data sites are provided. An exemplary method may comprise receiving a data object at a mirrored data site, the mirrored data site including one or more data nodes. The data objects are replicated to the one or more data nodes internally. Then, a data object reference associated with the data object is generated. The reference referring to the data object is queued for transmission to all other mirrored data sites. The data object reference associated with the data object is transmitted to the other mirrored data sites. When the data object is received at each mirrored data site, it is replicated to one or more data nodes within the site. After transmitting the data object, the data object reference is discarded.
