Understanding Cloud Storage

  • Last updated on

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

Barracuda Cloud Storage may only be used to mirror the data that is stored on the Barracuda Message Archiver to Barracuda Cloud Storage for off-site redundancy. Retention policies that you set on the Message Archiver appliance will be the same in Cloud Storage. Once you link your Barracuda Message Archiver to a Barracuda Cloud Control account, you can mirror all new and existing mail and then search, export, or forward that mail from both the Barracuda Message Archiver web interface and from Barracuda Cloud Control. Define Cloud Storage on the Advanced > Cloud Storage page in the web interface.

Hybrid Deployment

In hybrid appliance and cloud storage deployments, the Archiver tab in the Barracuda Cloud Control web interface is intended for basic functionality. Configuration changes for Barracuda Message Archiver appliances connected to cloud storage must be made from the local UI or Barracuda Appliance Control. In hybrid appliance and cloud configurations, end user access and searching should be done through the appliance.

Barracuda Cloud Storage Security

The Barracuda Message Archiver is deployed behind the customer’s corporate firewall and is protected by the same security measures that the customer uses to protect their primary data sources. All data transferred to and stored in the Barracuda Cloud is encrypted using AES 256-bit encryption. Multiple copies of the data are maintained using redundant storage within the same primary region.

Mirror in Cloud Storage

Barracuda Networks strongly recommends unstubbing your data before you mirror it to the cloud. Contact Barracuda Networks Technical Support for more information.

Select Mirror in the Cloud Storage section on the Advanced > Cloud Storage page to copy all new messages, including folder data, to Barracuda Cloud. 

Offline Access

If your on-premise Barracuda Message Archiver goes offline, the administrator can access the emails stored in the cloud by logging in to using the account that the cloud storage is connected to.
