System Requirements for Virtual Server Agent with Google Cloud Platform

The following requirements are for the Virtual Server Agent with GCP.

Virtual Server Agent Proxies

The Virtual Server Agent can be installed on GCP instances running the following operating systems:

  • Windows Server 2016

  • Windows Server 2012 R2


The VSA proxy must reside on the Google Cloud. More specifically, the VSA proxy must reside on the same project where the Guest VMs reside for backup and restore operations to be successful on the GSP. A VSA proxy residing on one project cannot perform backups or restores of guest VMs residing on a different project.

Firewall Requirements

Tunnel ports (for example, 8400 and 8403) must be opened in the security group for the instance to enable installation of the Virtual Server Agent to Google Cloud Platform instances and communication with the CommServe system.

If you deploy a CommServe host in an environment with firewalls, create a persistent route from the CommServe host to the VSA proxy, as documented in Setting Up Proxy Connections Using a Predefined Network Topology.

Specify the RESTRICTED setting for connections from the CommServe host to the VSA proxy and the BLOCKED setting in the CommServe node settings for the proxy. See Restricting or Blocking Connections for more information.

If a firewall proxy is installed, configure Internet options for the firewall proxy machine. On the HTTP Proxy tab of the Internet Options dialog box, enter the user name and password for the firewall proxy machine, using only the user name and not including the domain name with the user name.

Configuring a Firewall to Install the Virtual Server Agent on a Cloud VM or Instance

To deploy the Virtual Server Agent (VSA) or MediaAgent on a cloud VM or instance when other components (such as the CommServe host) are on premises <Category>, configure a Commvault firewall connection between the on premises components and the cloud VM or instance.
