Overview

You can achieve Backup proxy load balancing with Backup proxy pools.
The Backup proxy pool is a collection of backup proxies. Backup proxy pools eliminate the need to manually map the virtual machines to an individual Backup proxy. All the backup requests from the virtual machines mapped to a pool are assigned to backup proxies within the pool based on the load balancing mechanism.
You must ensure an optimum number of backup proxies with sufficient resources deployed in each pool.  If a Backup proxy within a pool is disconnected, the backup or restore job is assigned to the next available Backup proxy within the pool. For more information, see Resource Sizing for a Backup proxy.
A default Backup proxy pool is created for every registered Prism Element or Prism Central.  Any new Backup proxy deployed in the registered Prism is added to the default proxy pool. You can create new pools within the registered Prism and move backup proxies.

Note:You cannot rename or delete the default Backup proxy pool.

Best practices for creating Backup proxy pools

The following diagram illustrates the best practices for creating a Backup proxy pool.

As illustrated in the diagram:

• You must create the Backup proxy pools with respect to a data center. Typically, data centers are associated with a geographical region.
  Example:  If you have a data center 1 that is created for Australia, and data center 2 that is created for North America, you must create exclusive Backup proxy pools that are associated with the respective data center i.e. geographical region.
• Within a data center, there can be geographically distributed clusters, in such cases, you can create a separate Backup proxy pool for each cluster.
  Example:  A data center is dedicated to APAC. Within the APAC data center, there can be multiple clusters spread across geographies, for example, one in Australia, other in India. In such a case, create a separate Backup proxy pool for Australia and India.
• Ensure that the virtual machines that belong to a certain region are backed up by backup proxies deployed for the same region.
  Example:  If you are backing up virtual machines in the Australia region, ensure that they are backed up by backup proxies that are deployed in the Backup proxy pool for Australia.
• When you configure a virtual machine for backup, ensure that the virtual machine belonging to a specific data center is mapped to the Backup proxy pool created for that data center. This helps to avoid the data from traveling over WAN across geographical regions.
