Explanation

DD Replicator supports five replication topologies (one-to-one, one-to-one bidirectional, one-to- many,many-to-one, and cascaded). In many-to-one replication, whether with MTree or directory, replication data flows from several source DD systems to a single destination DD system. This type of replication can be used to provide data recovery protection forseveral branch offices on a corporate headquarter's IT system.
