AWS Backup now supports schedule-based network bandwidth throttling for VMware. This allows you to optimize network bandwidth used for backups and restores between your VMware environment and AWS. You can throttle the network bandwidth used by the Backup gateway for VMware backups, based on a schedule you set on the Backup gateway. This enables you to regulate network bandwidth use during peak hours to minimize network congestion and prevent you from using all your available bandwidth during peak hours.
