7 Replication
The Replication menu allows you to monitor and configure all aspects of replication. The following
options are available.
• Status (Replication)
• Virtual Tape Mappings (Replication)
• NAS Mappings (Replication)
• Partner Appliances (Replication)
• Local Appliance (Replication)
• Event History (Replication)
These pages allow you to monitor and configure replication. 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 StoreOnce Backup System Concepts Guide:If you are new to the HP StoreOnce Backup
System, it is a good idea to read this guide before you configure your system. It describes the
StoreOnce technology and advises how to plan the workload being placed on the HP
StoreOnce Backup System in order to optimize performance and minimize the impact of
deduplication, replication and housekeeping operations competing for resources.
• D2D Best Practices for VTL, NAS and Replication implementations: This guide describes best
practices and aslo includes examples using different backup applications.
Status (Replication)
The top part of this page shows the replication status summary of the appliance which may be:
• OK
• A target appliance is offline
• A mapped share (NAS) or slot pair (VTL) is not synchronized, or out of sync for a certain
number of days (hours), depending upon the settings for warning/critical out of sync hours
There is also a second line that indicates whether the appliance is licensed as a replication target
or not.
The central section of this page contains information about replication throughput and active
sessions. These tables show an average throughput over a period time so will not produce accurate
data straight away
The bottom half of the page contains three tabs, that show status details for:
• Current Issues such as: a target appliance is offline or a mapped share (NAS) or slot pair
(VTL) is not synchronized, or out of sync for a certain number of days (hours), depending upon
the settings for warning/critical out of sync hours
• Source Active Jobs
• Target Active Jobs
Click and highlight any of the status details to display more information about the issue.
