This article refers to the Barracuda Message Archiver firmware version 5.0 and higher running on Barracuda Message Archiver model 450 and higher. Mirrored systems must be the same model and run the same firmware version, but need not reside in the same location or network. Each Barracuda Message Archiver must function independently and accept and archive messages before it can be mirrored to another system.
You must complete all steps on each system you want to include in the mirrored configuration or message synchronization may not be bidirectional.
Step 1. Configure Barracuda Message Archivers for Mirroring
- On each system you want to include in the mirrored configuration, navigate to the ADVANCED > Clustering page, and in the Mirroring section, enter the following details:
Shared Secret – Enter an alphanumeric shared secret passcode; you must enter the same code on all Barracuda Message Archivers that you want to include in the mirrored configuration so that the systems ‘trust’ one another.
Mirroring Hostname (optional) – The name by which systems that mirror to this Archiver will attempt to communicate with it. If this field is empty, then the system IP address will be used.
Mirror this Archiver to – The IP address or host (DNS) name of an Archiver to which you would like this appliance to mirror messages
Click Add Mirror, and click Save at the top of the page.
Repeat these steps for each system you want to include in the mirrored configuration using the same shared secret on each system.
Step 2. Verify System Connectivity
Once the Barracuda Message Archivers are fully configured for mirroring, make sure that each system can see the other systems over the network:
Log in to each system, and navigate to the ADVANCED > Troubleshooting page. In the Network Connectivity Tests section, enter the hostname or IP address of the system you want to test in the Ping Device field, and click Begin Ping.
- Verify the other systems can be seen over the network. Once you complete the mirror settings and verify system connectivity for all Barracuda Message Archivers in the mirrored configuration, the configuration is complete.
Step 3. View Clustering Status
You can check the cluster status and transfer rate to the mirrored device from the BASIC > Dashboard page in the Cluster Status section.
