VBA: Network Throttling in VSPC
Network throttling will limit how much network usage can Veeam use during a cloud backup operation.
Prerequisite: you need to know your upload speed (upstream bandwidth). Use speedtest.net or another similar tool to know this data.
Log in to the console and go to Backup Jobs > Computers tab.
Click on the machine where you'd like to control bandwidth usage.
In the last row, set the bandwidth limit. Half or third of your upstream bandwidth is the usual recommended amount.
