Storage Resources utilizing data reduction can be replicated using any supported replication software, such as Native Synchronous or Asynchronous Replication to any supported destination system. All data replicated, regardless if it is local replication or to a remote system, is first restored to its original size then replicated to the destination. This method of replicating data reduction enabled storage resources ensures that all replication topologies are supported as if data reduction is not enabled on the resource. Replicating to systems which do not support data reduction and/or Advanced Deduplication is also supported, such as replicating to Dell UnityVSA or a physical Dell Unity system with a configuration which does not support data reduction and/or Advanced Deduplication.

Dell Unity Data Reduction and Advanced Deduplication can also be enabled on only the source, only the destination, or both the source and destination storage resources, depending on if the system and Pool configuration support Dell Unity Data Reduction and/or Advanced Deduplication. This allows the user to fully control where to implement data reduction. One example of a supported replication configuration is when utilizing Asynchronous Local Replication. The source storage resource may reside on an All Flash Pool and have data reduction enabled, but the destination may be on a large capacity Hybrid Pool which does not support data reduction. Another example of a supported configuration is when replicating a storage resource from a Dell UnityVSA system or a production system not utilizing data reduction, to a storage resource with data reduction and Advanced Deduplication enabled on a remote system. Replication can also occur between a resource created before the system was running Dell UnityOS version 4.4, and one after.
