Please verify that your backup policy explicitly includes retention settings for weekly and monthly backups. These settings must be configured during policy creation or modification to define how long these backup points are retained.
If your current backup policy was created directly from the Azure File Share page, it may have limited configuration options. I recommend recreating or editing your policy from the Azure Business Continuity Center, where more advanced retention settings (including weekly, monthly, and yearly retention) are available.
If you're not seeing any Protected Items in the Business Continuity Center:
Verify your Azure File Share is correctly associated with the intended backup policy.
Check if the backup job has run successfully and created recovery points.
Review for any configuration issues that might prevent the system from recognizing existing backups.
Go through your existing backup policies and confirm they include the retention rules for weekly and monthly backups.
