Azure Stack Infrastructure Backup Permissions

A really quick post on the permissions needed when configuring Azure Stack infrastructure backup: when I was configuring this according to the Microsoft documentation (https://docs.microsoft.com/en-us/azure/azure-stack/azure-stack-backup-back-up-azure-stack), there was no mention about the minimum permissions for Azure Stack needed to perform the backup.

After some experimentation, the account used to do this requires the Contributor role on the Default Provider Subscription – Reader is not enough.
