Backing up and restoring labels (sensitive or retention) and dlp policies in purview

Is there a way to backup and restore sensitive labels, retention labels or dlp policies with the security and compliance portal (purview)? The documentation is not thorough when it comes to a scenario in which an admin deletes any of these.  I'd like to think there's a way to back these things up in the event of accidental deletion or from a change management perspective (making a change and want to roll back).  

Thanks!
