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 VMs in your environment, eliminating the need to install agents on guest VMs.
The Virtual Server Agent (VSA) must be installed on a physical or virtual machine running supported versions of Linux or Windows. You must add at least one Virtual Server Agent (VSA) proxy for the FusionCompute Virtual Resource Manager (VRM). Additional proxies can be added as needed.
You can install the MediaAgent on the same machine as the CommServe system or on a separate machine.
