How to Link the Barracuda Message Archiver to Cloud Storage

  • Last updated on

This article refers to Barracuda Message Archiver version 5.0 or higher.

Cloud Storage allows you to rotate or mirror data from the Barracuda Message Archiver to the Barracuda Cloud.


  • You must have a Cloud Storage Subscription available from Barracuda Customer Services.
  • If the appliance is located behind a corporate firewall, you may need to open the following ports to allow communication between the appliance and Barracuda Networks:
    • Ports 80/443 and 1194 outbound for both TCP and UDP are required for communication 
    • Ports 5120-5129 are used to replicate data to Barracuda Cloud Storage; contact Barracuda Technical Support to restrict outbound network traffic on these ports to only reach Barracuda Networks

Use the following steps to link your Barracuda Message Archiver to a Barracuda Cloud Control account:

  1. Log in to the Barracuda Message Archiver web interface, and go to Advanced > Cloud Storage:

  4. In the Location page, enter the City, State, and Country where your mail server is hosted; your account can link to only one location.
