is it possible to make a backup of an azure analysis service on a storage account which ist protected via firewall rules? I have set the exception “allow trusted Microsoft services to access this storage account”. But If I try to set the backup on the azure analysis service side I get this error message:
Invalid backup blob container xxxxx: 'The remote server returned an error: (403) Forbidden
I don't think you can do it via only setting the exception "allow trusted Microsoft services to access this storage account” since azure analysis service is not included in the trusted Microsoft services.
If you have selected allow access from selected network in the firewall and virtual networks of the storage account, actually you have enabled the firewall of the storage account, so you have a forbidden error.
