DXi4701 Replication
The DXi4701 provides data replication capabilities that you can use as
an integral part of a disaster recovery plan. Replication allows you to
configure the DXi4701 to create a copy of your data on another DXi
system at scheduled intervals (or manually as needed).
In the event of a disaster in which the original data is lost, you can
quickly recover the replicated data on the remote system, allowing your
business to resume normal operations. Once the original system is
available again, you can restore all data back to its original location.
Note: Quantum recommends that you configure and start replication
before storing large amounts of data on the DXi4701.
Note: A DXi4701 can only replicate data to a DXi that supports the
same protocol as the DXi4701 (NAS or VTL). That is, a DXi4701
NAS system can only replicate data to a DXi that supports NAS.
Similarly, a DXi4701 VTL system can only replicate data to a DXi
that supports VTL.

replication capabilities of the DXi4701:
