Thank you very much and have a great one!

Hi ​@ethouin, 

Thank you for posting in the community! There is .laf files in the back up and restore functionality for premium accounts. Revision history doesn’t transfer over through .laf files, it acts as a new document and will begin once the document is uploaded into account. 

Thanks for the information. 
Is there another way to completely export the revision history itself?

Hi ​@ethouin, 

Thank you for the reply. There is not currently a functionality that allows you to export the revision history. However, sharing your document with other people and give other users access to the revision history. You can also create a new document from versions in your history, and then export those documents.
