Backup Method
This defines where the backups actually go. There are three options:
  1. Backup to File: Create the backups as files in /var/BACKUP
  2. Backup to SCSI Tape Drive: Back the files up to /dev/nst0
  3. Backup to IDE Tape Drive: Back the files up to /dev/nht0
Any changes made here will effect all subsequent backups.
