Attempting to use Red Hat Linux 8/WebMin Filesystem Backup module fails every time, regardless of what I am trying to back up. Even a basic, static backup fails. For this test, I'm trying to back up  the /usr/local/apache/conf directory to /usr/local/backup.
Receiving this error:
Performing backup of /usr/local/apache/conf to /usr/local/backup ..

  DUMP: Date of this level 0 dump: Fri Jun 27 18:42:49 2003
  DUMP: Dumping /dev/sda1 (/ (dir usr/local/apache/conf)) to /usr/local/backup
  DUMP: Added inode 8 to exclude list (journal inode)
  DUMP: Added inode 7 to exclude list (resize inode)

  DUMP: estimated 1039 tape blocks.
  DUMP: Cannot open output "/usr/local/backup".
  DUMP: fopen on /dev/tty fails: No such device or address
  DUMP: The ENTIRE dump is aborted.

.. backup failed!

Linux newsgroups offer that the /dev/tty error occurs when something in the file list changes between compiling the list and writing the backup, but ../conf has only static files. I could see if I were backing up whole filesystem, where many things could be modified as the file list was being generated, but a tiny static directory?

I created /usr/local/backup just for this test.
/usr/local/backup is chmod 777.
I'm root.
It doesn't matter what if/of I'm using, the  same /dev/tty error always appears and the backup fails.

Thanks in advance for any help.
