Bandwidth throttling in DPM is set on an individual protected computer bases. This allows the admin to tailor throttling requirements to the protected computer, based on network speed, business policy, geographical location and so forth.
For example: An admin may need to configure endpoint laptops to be backed up only during the working day, limiting bandwidth when the endpoint is potentially outside the organisation.
To throttle network bandwidth usage for a protected computer in DPM 2012 R2, begin by opening the DPM console. Select the Management tab, then click on the Agents link in the top left console panel which will display all protected computers in the window on the right as well as changing the DPM ribbon to make visible the Throttle computer button.
Select the protected computer that requires network throttling and then click the Throttle computer button, this will pop up the Throttle wizard.
Check the Enable network bandwidth usage throttling check box and then configure the appropriate settings. This is done by establishing Work hours and Work days then assigning throttling limits to each period of time.
And its as simple as that! 🙂
