The Symantec Backup Exec Agent for Microsoft Hyper-V (Agent for Microsoft Hyper-V) is installed as a separate, add-on component of Backup Exec. The Agent for Microsoft Hyper-V is installed on the Microsoft Hyper-V host. If your Backup Exec media server is also your Microsoft Hyper-V host, you can install the Agent for Microsoft Hyper-V when you install Backup Exec. Or, you can install it after Backup Exec has been installed.
If Backup Exec is not installed on your Microsoft Hyper-V host, you must push-install the Remote Agent for Windows Systems to your Microsoft Hyper-V host. You do not need to install the Agent for Microsoft Hyper-V on virtual machines. However, a license key is required on the media server for the Agent for Microsoft Hyper-V. The Remote Agent for Windows Systems is included with the Agent for Microsoft Hyper-V.
