Put a filesystem on the Jaz and dump to files. I have been doing this
for a long time. Here is my script,
#!/bin/sh
#
# jazdump - Weekly dump to a Jaz disk.
#
# Usage: jazdump level
#
# Toss a Jaz disk in the drive, su to root
# and execute this command. Enter the level
# of the dump. The Jaz disk is expected to
# have a UFS format. Just change the 'mount'
# command if it were *gag* MSDOS,
#
# mount -t msdos /dev/sd0 /mnt/jaz
# ^^^^^^^^
# If the fdisk or disklabel info for wd0 has
# changed, those are saved as well.
JAZDEV=/dev/da4
if [ -z $1 ] || [ $1 -gt 9 ] || [ $1 -lt 0 ]; then
echo "jazdump: dump level must be 0-9, invalid level: $1"
exit 1
fi
if ! mount $JAZDEV /mnt/jaz; then
echo "jazdump: could not mount Jaz disk, no dumps done"
exit 1
fi
# Here go the dumps. Remember add or remove any
# additional filesystems here.
cd /mnt/jaz
umask 222
dump -au -$1 -f - / | gzip > root_$1.dmp.gz
dump -au -$1 -f - /usr | gzip > usr_$1.dmp.gz
dump -au -$1 -f - /var | gzip > var_$1.dmp.gz
dump -au -$1 -f - /home | gzip > home_$1.dmp.gz
echo ""
echo "jazdump: all dumps complete"
####
# I've cut the disklabel and fdisk stuff for brevity
####
# We need to get out of the directory to umount
# the drive. Might as well go $HOME.
cd
if umount /mnt/jaz; then
echo "jazdump: Jaz unmounted."
else
echo "jazdump: could not unmout Jaz disk."
fi
exit 0
If you need help putting a filesystem on a Jaz, try the list
again. It's not a big deal.
