Select Replication from the StoreOnce menu item to display all aspects and tasks associated with
replication.
There are four tabs on the main Replication page and two further Navigator options for configuring
VTL and NAS mappings. The default tab when you select this option from the Navigator is the

NOTE: With the current version of the software there are no equivalent CLI commands available
for the tasks described in this section.
If you are new to replication we strongly recommend that you read the following documents, which
are available from the HP web site. They provide a detailed discussion about replication deployment
strategies and terminology and include examples using the Replication and Recovery wizards.
HP Best Practices for VTL, NAS, StoreOnce Catalyst and Replication implementations: This
guide also describes best practices and includes examples using different backup applications.
NOTE: A license is required for replication on the target appliance.

What is an appliance?

Replication can take place between multi-node, single-node, and single-node VSA StoreOnce
Backup systems. The GUI for both refers to both Replication Targets and Sources as appliances.
It is important to understand the different meaning of appliance within the multi-node, single-node,
and single-node virtual environments.
In a single-node StoreOnce Backup system, the appliance is the physical device or server that
contains the data to be replicated. All mapping is done using the physical IP addresses of the
target and source StoreOnce Backup systems.
In a multi-node StoreOnce Backup system, the appliance is the service set that contains the
data to be replicated. This means that each B6000 Backup system has at least two service
sets that can be selected as appliances. (A fully expanded HP B6000 Backup system would
