Altaro VM Backup does not offer throttling natively as it stands, but fortunately Windows gives you the functionality to do this built-in.
All you have to do is open PowerShell and run the following command on the Altaro machine and ALL Hyper-V Hosts:
Syntax for Offsite Backups:
New-NetQosPolicy "AOS Throttle" -IPDstPortStartMatchCondition 35116 -IPDstPortEndMatchCondition 35117 -ThrottleRateActionBitsPerSecond 10000000
Syntax for Replication:
New-NetQosPolicy "AOS Replication Throttle" -IPDstPortMatchCondition 35120 -ThrottleRateActionBitsPerSecond 10000000
The ThrottleRateActionBitsPerSecond must be specified in bits. So for instance;
- 3 Mbps = 3000000 Bits
- 10 Mbps = 10000000 Bits
- For VMware hosts, this only needs to be applied on the machine running Altaro.
- To throttle offsite backups for Azure Cloud Storage, please contact the Altaro support team.
