Deployment - Virtual Server Agent for Amazon

For streaming backups, the Virtual Server Agent (VSA) should be installed on an instance hosted in Amazon. The VSA proxy must be in the same Amazon account and located in the same region as the instances to be backed up.

For restores, the VSA proxy can be an Amazon instance or an external machine.

For IntelliSnap backups and restores from IntelliSnap jobs, the VSA proxy can be an Amazon instance or an external machine.

If the VSA proxy used for a restore is an Amazon instance, the proxy and the destination instance for the restore must be in the same zone.

The proxy machine must be able to connect to ec2.amazonaws.com. To route communications through an HTTP or HTTPS proxy, provide proxy information in the CommServe Control Panel, on the HTTP Proxy tab of the Internet Options dialog box. To use an HTTPS proxy, you must provide authentication details.

For more information, see System Requirements.

Components

Commvault uses the following components to support data protection and recovery operations:

  • CommServe host: Provides management, status, and reporting for protection operations. The CommServe user interface includes the CommCell Console and CommCell Browser. Ideally the CommServe library should be located in Amazon, but it can also be hosted externally.
  • Virtual Server Agent (VSA): The Virtual Server Agent can be installed on one or more machines, so that those machines can serve as VSA proxies. A VSA proxy manages backup and restore operations for guest instances in your environment, eliminating the need to install agents on guest instances.
    • For backups, the VSA must be installed on an Amazon instance in each region to be protected. Each VSA proxy can protect instances in the same region.
    • For VM conversion and restores, the VSA can be installed on an Amazon instance or on an external machine. 

    You can configure application-aware backups using the Virtual Server Agent to protect application data without installing guest agents on instances.

  • MediaAgents: MediaAgents can reside in Amazon instances or on servers in the physical environment. MediaAgents on the VSA proxy instance might provide better performance.
  • Web Console: If VM Lifecycle Management is configured, end users can use the Web Console to create and manage their own virtual machines. Administrators can create VM provisioning templates and policies to support self-service VM provisioning for end users.
