Server 1 uses storages A, B, C, D
Server 2 uses storages C, D, E
Server 3 uses storages B, C, D
The VA can be deployed to either C or D. If there is no storage shared by all the servers, you can
import the VA manually into any of the hosts. This will work, but backup performance will be far from
optimal.
After deployment, the agent virtual appliance can appear on any of the hosts included in the cluster,
depending on how the load balancing is configured.
Moving the agent VA around the cluster
The agent’s work is not affected when the Distributed Resource Scheduler (DRS) migrates the virtual
appliance to another host.
Creating a cluster of servers that already have agents
It is recommended that you remove Agents for ESX/ESXi from all but one of the servers. Retain the
agent whose VA resides on the shared storage. Restart the VA so that it becomes aware of the
cluster.

Privileges for VM backup and recovery
Once Agent for ESX/ESXi is deployed to a vCenter's host or cluster, any user of the vCenter Server can
connect a management console to the agent. The scope of available operations depends on the
privileges a user has on the vCenter Server. Only those actions are available that the user has
permission to perform. The below tables contain the privileges required for backup and recovery of
ESX virtual machines and, additionally, for virtual appliance deployment.
If the agent was deployed directly to an ESX/ESXi host or manually imported to the host, and you
want the vCenter users to be able to connect to the agent and the below privileges to take effect,
connect the agent to the vCenter Server rather than to the ESX/ESXi host. To change the connection,
access the virtual appliance GUI using the vSphere Client and specify access credentials for the
vCenter Server in the
ESX(i)/vCenter
setting.
Privileges on vCenter Server or ESX/ESXi host
Outlined in the below table are the privileges a vCenter Server user must have to perform operations
on all the vCenter hosts and clusters.
To enable a user to operate on a specific ESX host only, assign the user the same privileges on the
host. In addition, the

privilege is required to be able to back up virtual machines of
a specific ESX host.
