Does anybody know a good cheap backup program for open files that will let me back up to disk. I need something to backup a server on a USB HDD and it needs to get open files. Thanks.

I don't know of any cheap ones. Veritas is the only one I have used besides IBM products. Both are very pricey.

I have veritas 8.0, but it won't point to a drive letter or UNC.

backing up open files is what cost you money. Here is an interesting idea http://www.winnetmag.com/Windows/Article/ArticleID/41256/41256.html.
