In the Jira bug reporting system it says to back up your games so you can switch back and forth between Beta and Production. Everytime I back up my BETA game it is 0 KB. It seems I cannot export my world. I have gone into the microsoft.minecraft folder and found the game folder which I copied to another directory. I am hoping I do not have to rely on this and that someone knows how to actually export/save the file in game so I can restore once I return to beta.
