Norton Ghost 15, delete old Files and Folders backup

Ghost run on 1 PC only, backup destination is external LAN disc.

I defined 2 jobs. My computer backup and My Files and folders backup. Lately I delete second job, but I can see in Status all previous File and Folders backup and they are on LAN disc too.

Because I don't need these files I would like to clean up LAN disc and Status view.

I don't know how delete Files and Folders backup in Status neither on disc.

Can you give me a piece of advice what to do?

 

Thanks
