Retroactive ongoing processing evaluates all files under a folder for file metadata updates and policy processing whenever there is any change in the parent folder. API Data Protection does a retrospective scan of such parent folders when an ongoing change occurs.
Important
API Data Protection triggers a retroactive ongoing scan for share, un-share, and move notifications at a folder level only.
Note
Retroactive ongoing processing is enabled by default for Dropbox and Office 365 OneDrive cloud apps.
