In A/UX 2.0, the "c" option to dump.bsd did not work properly, and it
was necessary to specify the media size.  I used the following command
to do a complete (level 0) backup.

/etc/dump.bsd 0cubsf 16 37m /dev/rmt/tc1 /dev/dsk/c0d0s0

The meaning of the options is:
0	do a level 0 dump (change as needed)
c	set for Apple Tape Backup 40SC
u	write dump date to /etc/dumpdates
b 16	use blocking factor of 16k
s 37m	media size is 37 megabytes

/dev/rmt/tc1  is the tape device (replace 1 with correct SCSI id)
/dev/dsk/c0d0s0 is the file system being backed up (change as needed)

The "c" option is fixed in A/UX 2.0.1, so you can use a simpler
command, like the following:

/etc/dump.bsd 0cuf /dev/rmt/tc1 /dev/dsk/c0d0s0
