For a new or existing subclient, you can define rules or select objects to include or exclude instances.
Automatic discovery enables you to automatically select instances for a subclient based on criteria such as a region, zone, tag, instance name pattern, guest OS, guest DNS hostname, or power state.
Filtering enables you to exclude instances 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 instances to be included for each subclient.
