Hi Keld_Mollnitz
If DB Unload has run then the object has been deleted from the database. There is no way to restore it directly.
One (complicated) way to achieve this would be to use a backup copy of the DB, and start an AE instance that runs on this DB, then export the object.
Also, to prevent this from occurring you can run DB Unload with "-K" parameter so that the recycle bin does not get emptied.
Best regards,
Antoine
