How to manage on-premises to Azure protection network bandwidth usage

When you enable on-premises to Microsoft Azure protection by using Azure Site Recovery (ASR), the network bandwidth can be managed by using the methods in this article.

Manage the network bandwidth for on-premises virtual machines

The Microsoft Azure Recovery Services Agent that's installed on the Hyper-V host for On-Premises VMM Site to Azure or On-Premises Hyper-V Site to Azure is configured to use the default Internet bandwidth usage settings. 

An administrator can configure individual Hyper-V hosts to use different network bandwidth settings. After these configurations are implemented, you should monitor network bandwidth usage for several days to make sure that the configured settings optimize your usage.

Detailed steps

Value Name: DownloadThreadsPerVM
Value Type: REG_DWORD
