HP StoreOnce VSA Backup System User Guide (TC458-96025)

5 Replication functions
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
VT mappings and NAS mappings. The Status tab is the default.
Users with an Admin login can create mappings and configure replication. Operators can use this
page to view replication settings.
Replication settings
• Status tab (page 52)
• Partner Appliances tab (page 52)
• Local Settings tab (page 57)
• Event History tab (page 60)
Replication mappings
• VT Mappings (Replication) (page 61)
• Recovering a source appliance, VTL devices (page 67)
• NAS Mappings (Replication) (page 70)
• Recovering a source appliance (NAS shares) (page 76)
Replications actions are applied and monitored at appliance level. For a definition of an appliance,
see What is an appliance (page 50).
NOTE: With the current version of the software there are no equivalent CLI commands available
for the tasks described in this section.
HP strongly recommends reading the HP StoreOnce Concepts and Configuration Guidelines, which
is available from the HP web site. These guidelines provide a detailed discussion about replication
deployment strategies, terminology, and include examples using the Replication and Recovery
wizards.
NOTE: A license is required for replication on the target appliance.
What is an appliance?
Replication can take place between different models of StoreOnce Backup systems. The GUI refers
to both Replication Targets and Sources as appliances, so it is important to understand the different
meanings of “appliance” across the product models.
• In a StoreOnce 2700, 4500, 4700, and 4900, 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 StoreOnce VSA, the appliance is the virtual device or server that contains the data to be
replicated. All mapping is done using the IP addresses of the target and source StoreOnce
Backup systems.
• In a StoreOnce 6500 and B6200, the appliance is the Service Set that contains the data to
be replicated. This means that each StoreOnce 6500 or B6200 Backup system has at least
two Service Sets that can be selected as appliances. (A fully expanded HP StoreOnce 6500
or B6200 Backup system would have eight Service Sets.) All mapping is done using the virtual
IP addresses of the target and source Service Sets.
Within this section of the GUI, the terms appliance and Service Set are synonymous.
