gain makes it practical and cost-effective for users to replicate backup data over WANs for secure, network-
based disaster recovery protection, and it lets users combine rapid, local restores with sound disaster
recovery protection.
With DXi-Series replication, users can transmit data from a single site or multiple sites to a central location
using any DXi model. DXi-Series replication is an asynchronous, automated background process that
includes encryption of data in transit. This model for protecting the distributed enterprise allows users to
combine disk, replication, and tape for an optimal combination of performance, simplicity, and security.

.
Note:
A DXi4700 can only replicate data to a DXi that supports the same protocol as the DXi4700
(NAS or VTL). That is, a DXi4700 NAS system can only replicate data to a DXi that supports NAS.
Similarly, a DXi4700 VTL system can only replicate data to a DXi that supports VTL.
