For a new or existing subclient, you can define rules or select objects in the cluster to include or exclude virtual machines.
Automatic discovery enables you to automatically select virtual machines for a subclient based on criteria such as a VM name pattern, power state, or storage location, or by specifying a specific VM.
Filtering enables you to exclude virtual machines or VM disks based on similar criteria. You can define filters on a subclient (only applies to that subclient) or on a backup set (applies to all subclients under the backup set).
By combining automatic discovery and filtering, you can precisely target virtual machines to be included for each subclient.
