Post Backup Script to reset keys to Normal mode

I've just been onto Symatec's support about our Enterprise Vault. When trying to store or restore e-mails from vault they just hang there and do nothing.
I did a scan of the EV server and sent it to support and they came back with this:

"Hi Edd,
 From the Deployment scanner i can see that the server is set to read-only backup mode still.
   Registry Settings    
  Registry Key   Value  
  EnableArchive     *** READ ONLY ***  
  EnableExpire     *** READ ONLY ***  
  EnableReplayIndex     *** READ ONLY ***  
  EnableRestore     *** READ ONLY ***  
  EnableFileWatch     *** READ ONLY ***  
  EnableCrawler     *** READ ONLY ***  
  EnablePSTMigrations     *** READ ONLY ***  
 If the backup has completed then please reset the keys to normal mode using the Post backup script if you have one otherwise update each of the keys."

Problem is I have no idea how to setup these scripts, and the suppot guy isnt being very supportive from this point!
Could anyone give me some idea of what to do?

We use Backup Exec so will need to add post scripts to that.

Thanks,
Edd...
