<#When populating Azure data stores, sometimes I find it is simplest to copy a great deal of data over the network, but I do not have authorization to monopolize the outbound pipe. In those cases, I copy data with AzCopy.exe on one server, and I throttle those copy jobs by setting up a Quality of Service policy on that server. This solution relies on running all copy jobs through the server that has this policy enabled. It should throttle multiple parallel copy jobs to the TOTAL ThrottleRateActionBitsPerSecond you specify. ActiveStore means this does NOT persit after reboots. Pick a rate that is appropriate to your environment.
Remember that when setting up QOS policies, you need to throttle the thing DOING the copying, not the thing INVOKING the thing doing the copying. I.e., if you run your azcopy.exe job in PowerShell, don't throttle PowerShell, throttle azcopy.exe#>
