SharePoint: Backup and Restore of Folder-Level Permissions​ 

The enhanced SharePoint backup preserves folder-level permissions, ensuring that confidential folders such as HR and Finance retain their original access controls during recovery. This prevents unintended access and helps maintain compliance.

Folder-level permission backup is disabled by default. An administrator must contact Customer Support to enable this feature. Once enabled, folder-level permissions are included starting with the next backup cycle. This feature is disabled by default and applies only to backups taken after it is enabled.
