11.1 ETERNUS CS800 Replication Overview
The ETERNUS CS800 provides data replication capabilities that you can use as an integral
part of a disaster recovery plan. Replication allows you to configure the ETERNUS CS800 to
create a copy of your data on another ETERNUS CS800 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.
Additional Information
Fujitsu Technology Solutions recommends that you configure and start replication before
l
storing large amounts of data on the ETERNUS CS800.
An ETERNUS CS800 can only replicate data to a ETERNUS CS800 that supports the
l
same protocol as the ETERNUS CS800 (NAS or VTL). That is, a ETERNUS CS800
NAS system can only replicate data to an ETERNUS CS800 that supports NAS.
Similarly, an ETERNUS CS800 VTL system can only replicate data to an ETERNUS
CS800 that supports VTL.
