Before you can backup your virtual machines, you have to register the Hyper-V host on which you create and manage virtual machines. During registration, Druva generates an activation token that activates the Enterprise Workloads agent installed on your host. Activation ensures that Enterprise Workloads agent establishes a persistent connection with Druva Cloud and registers your host with Druva. After your host is registered, backup is enabled for the host on which the agent is installed. The Enterprise Workloads agent:

scans your host and requests the VSS service for the virtual machine recovery point
backs up the recovery point on the cloud
restores data from the cloud when you request it

For an overview of configuration steps, see:

This article contains the following sections:

Step 1: Download the agent and generate activation token

For agent version 7.0.0 and later
- EnterpriseWorkloadsAgent.exe hyperv activate --gov-cloud --token 111111AAAAAA
- EnterpriseWorkloadsAgent.exe hyperv configure --type standalone
The --scvmm_fqdn parameter is applicable for System Center Virtual Machine Manager based host only. It is not applicable for a standalone host or a host in a cluster.
The --user and --password parameters are not required for standalone hosts.
In place of the --type, --user, --password, and --scvmm_fqdn parameters, you can use -e, -u, -p, and -f respectively.
If you move a host from one cluster to another after registration, the host appears as disconnected in the Management Console.
By default, the server is registered using its Fully Qualified Domain Name (FQDN). In addition, you can use the --ServerName or -d parameter to register your host with a name. The server name is not case-sensitive. You cannot have one server registered as "ABC" and another as "abc". Druva will display the error message "Server display name already exists. Cannot register the server with same display name". You can add the -d parameter to register the server with a different name.
You can upgrade Enterprise Workloads agents to their latest available version. For more information, see Upgrade the agent.
If you are using SCVMM for managing virtual machines on Windows Server 2008 and Windows Server 2008 R2 hosts:
- When you activate the Enterprise Workloads agent, select the type as standalone or cluster (based on your setup). Do not select the type as scvmm to register the hosts through SCVMM.
- Phoenix does not support registration of the Microsoft Windows Server 2008 and Microsoft Windows Server 2008 R2 hosts through SCVMM.

If you want to update the credentials later:
