Performing File Share Backup
One backup policy can be used to process multiple Azure file shares within different regions, but you can back up each Azure file share with one backup policy at a time. If an Azure file share is added to more than one backup policy, it will be processed only by a backup policy that has the highest priority. Other backup policies will skip this Azure file share from processing. For information on how to set a priority for a backup policy, see Setting Backup Policy Priority.
If you plan to receive email notifications on backup policy results, configure email notification settings first. For more information, see Configuring Global Notification Settings.
