Hi there,
There is a reason why beta software shouldn't be used in a production environment...saves you the effort of having to redo everything again.
That said, look at backing up everything in your Data and Catalogs folders for a start, along with your SQL database for good measure.
If you have anything left of your beta trial, load up the SQL agent and backup the SQL DB that way. To back up the Data and Catalog folders, you need to stop the BEWS services.
Laters!
