Throttling Rules Not Being Applied

• Traffic can only be throttled between backup infrastructure components where the Veeam Data Movers are deployed. These components differ depending on a data protection scenario. For more information, review the table within the Veeam Backup & Replication User Guide.
• By default, traffic throttling does not apply to restore tasks.
  
  Starting in Veeam Backup & Replication 12, the option "Never throttle any restore activity" was added to the traffic throttling rules. When this option is unselected, the traffic throttling rule will apply to restores.
