Configuring DPM agent throttling in Microsoft System Center DPM allows you to restrict the amount of network bandwidth consumed by DPM during the execution of a backup synchronization job. Managing network bandwidth helps to ensure that DPM is not using all the available bandwidth and there is sufficient bandwidth available to support other applications. However, there is an impact when you start to manage bandwidth usage and that is that the backup synchronization jobs themselves will take longer to execute.
Microsoft System Center DPM manages network bandwidth at the agent level. When managing network bandwidth usage, start to think about limiting the amount of bandwidth used, in terms of the maximum amount of data to be transferred on a per-second basis. To be able to enable network bandwidth throttling, you must have the DPM protection agent deployed.
