Automating backup in Win2K server?

Hello, all. I’m trying to make automated backup as simple as possible for my clients using the native 2K server backup GUI scheduler. What I would like is for them to simply swap tapes each morning and not have to intervene at all in the UI. What prevents this is a prompt that backup throws asking “Do you want to overwrite the media labeled “10, Feb. 2002”? I’ve checked all the config options in the backup GUI and can’t seem to avoid getting this prompt. I know I could use AT commands and a.bat file, but would like to know how to do this with just the GUI. Anybody have any ideas? Don
