Thank you for the update, better to learn it here versus trial and error. Please consider the option to make it an optional plugin. Users would have to visit the website, read the warning / notice / disclaimer no support will be provided , then download the api and install it manually.

Hello, I was running it from a remote desktop session, and it was 30 seconds that the app would seem to have frozen before the backup would start. I've restarted the server and the progress bar starts immediately. Thanks for your help.

Bad decision. Let the client decide if the throttling is too much of an issue. I get 2mbps upload (have 10 provisioned) but so what. Once the initial sync has completed, daily sets run overnight and is not a concern. We have 100TB of space available on our plan, and its free. So much to like about the software, but I am sorry but this is a deal breaker for us as well. Need OneDriveForBusiness and Sharepoint compatibility.
