Performing File Share Backup
To produce snapshots of Azure file shares, Veeam Backup for Microsoft Azure runs backup policies. A backup policy is a collection of settings that define the way snapshots are created: what data to protect, when to start the snapshot creation process, and so on.
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.
