I must be disagreeable again.  Here's my notes on a raw-file backup and
verify which I did last January (using afio instead of tar):


///////
time find / /usr /u -xdev | afio -ozZ -b32k -c256 -M16m -T1k /big/fbsdbackup
cd /big/fbsdbackup-dir; afio -izZ -b32k -c256 -M16m -T1k /big/fbsdbackup
cd /big; burncd -f /dev/acd0c -s 2 -e blank data fbsdbackup fixate 
diff -r /big/fbsdbackup-dir /
cd /big/fbsdbackup-dir; time afio -rzZ -b32k -c256 -M16m /dev/acd0c
///////

I might have gotten lucky by creating a raw file that was a multiple
of the device block size (2k), but the "burncd" man page says that
pads short files so file size shouldn't be a problem.  Maybe it is.
