Do you have your database backup with latest Date?
i dont have the database backup
Than its not possible to export the policies which is currently in your ePO console.
Always back up your database. We have a large organization, so our SQL server is not on the same box as EPO, and we back it up nightly. I also have a habit of exporting all my policies for future reference, so, in case I delete a policy by accident, or I want to go back and look at an old policy that I had purged, I just restore the XML file. I think it took me 15 or 20 minutes to back up all my policies. BTW how does a database just "get deleted"? Don't answer that.
So, I guess you will have to recreate your policies from scratch also. Good luck!
