A Virtual Server Agent proxy (VSA proxy) manages backups for a hypervisor. A File Recovery Enabler for Linux (FREL) acts as a MediaAgent to write Linux file system backup data to storage, or to read backup data from storage.
VSA proxies and FRELs are servers. You can deploy a VSA proxy by adding a server or by adding Commvault software to an existing server.
The following use cases apply for VSA proxies and FRELs:
-
Each VSA proxy must have the Virtual Server software package installed.
-
For VSA proxies that support IntelliSnap, install both the Virtual Server software package and the Media Agent software package.
-
A Linux MediaAgent can be automatically configured to serve as a FREL.
For more information, see Automatic Configuration of a MediaAgent as a Linux File Recovery Enabler (FREL).
-
For hypervisors that support Linux proxies, you can install the Virtual Server software package on the Linux MediaAgent that is configured as a FREL, so that the same server can also serve as a VSA proxy.
Proxy Requirements by Hypervisor
-
Alibaba Cloud: An Alibaba Cloud instance in the zone to be protected.
-
Amazon: An Amazon instance in the region to be protected.
-
Azure: An Azure virtual machine in the region to be protected.
-
Google Cloud Platform: A Google Cloud Platform instance in the region to be protected.
-
Nutanix AHV: A virtual machine in the Nutanix cluster.
-
OpenStack: An instance in the OpenStack data center.
-
Oracle Cloud Infrastructure: An Oracle Cloud Infrastructure instance.
-
Oracle VM: A virtual machine hosted on an Oracle VM Server.

For VMware, the backup server where Commvault is installed is automatically selected as a default proxy. As needed, you can add additional physical servers or VMware VMs and configure them as proxies.
