No there isn't. If you use NTBackup, you will need to use 1 media. You could well create a .bkf file on the server and try to compress the file a bit. After that, you should be able to burn it to the DVD. There is also a program called File Splitter, this program can split a file into two files, so the bkf file could be split within two files.
Still, if you have these large of files and you need a reliable back-up, then i would choose to buy a tape drive. If you have time to kill and create the back-up manually, you could use a DVD disk.. But tapes are much better for those amounts of data,,
