Support For Vcenter Clusters - ACRONIS BACKUP AND RECOVERY 10 ADVANCED SERVER VIRTUAL EDITION - UPDATE 3 User Manual

Monitoring the deployment progress and result
Creating or updating virtual appliances may take some time. Watch the progress of the operations at
the bottom of the virtual machines' views underneath the Information bar. After a virtual appliance
is created and registered, a corresponding group of virtual machines appears on the management
server.
If the deployment completed but the group of virtual machines is missing
Access the virtual appliance console using the vSphere/VMware Infrastructure client and check the
agent configuration. Configure the agent manually, if required, as described in "Installing ESX/ESXi
virtual appliance." Add the virtual appliance to the management server manually as described in
"Adding a machine to the management server (p. 314)."

Support for vCenter clusters

In a vCenter cluster, a single Agent for ESX/ESXi backs up virtual machines hosted on all the cluster's
hosts.
Deploying Agent for ESX/ESXi to a cluster
When configuring the agent deployment from a management server, you can select a cluster as a
regular ESX host. The agent virtual appliance (VA) is deployed to a storage shared by all the cluster's
hosts. Normally, this is an NFS share or a SAN-LUN attached to each of the hosts.
Let's assume that the cluster contains three servers.
 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.
7.1.4.5 Support for VM migration
This section informs what you can expect when migrating virtual machines within a datacenter using
vCenter Server migration options. Performance considerations apply to both "hot" and "cold"
migration.
