Q: by 'restore DVD', do you mean 'DVD containing the backup dump', or 'a
bootable DVD that mounts itself and mkfs/mkswap/restore/grub and all that'?

#
#
# I'm creating a restore DVD and it is taking a very long time
# to restore
# the data. It takes longer to restore than it did to install
# the system.
#
# I'm using dump/restore to do the archival and restoration. When I do
# create the backup I am creating it with the option '-j9'.
# This adds the
# highest level ob bzip2 compression. I am not concerned with the
# resources that takes since the system is a 3.0P4 with 1mb
# cache. It has
# plenty of horsepower to do the restoration.
#
# What I can not figure out is why it is taking so long.
#
# Here is the data:
#
# #1 Restore DVD
#
# 12x CD-RW used for testing and not wasting blank CD-Rs
#
#
# #2 disk usage and size after restore
#
# Filesystem Size Used Available Use% Mounted on
# /dev/root.old 891.0k 387.0k 504.0k 43% /initrd
# /dev/hdc 651.2M 651.2M 0 100% /initrd/cd
# /dev/loop0 89.7M 89.7M 0 100% /
# none 501.5M 3.3M 498.2M 1% /mnt/rw
# /dev/md0 180.0G 1.6G 169.1G 1%
# /mnt/rw/tmp/md0
#
# I'm only restoring 1.6G of stuff
#
#
# #3 Time it took to do resotre:
#
# *************************************************
# * Restoration Complete! *
# *************************************************
# Restoration took 15903 seconds
#
# That is a very long time
#
# #4 Script used

# mount -t ext3 /dev/md0 /tmp/md0 || exit 6
# echo "Restoring files (this may take a while)...."
# cd /tmp/md0

# echo "Restoring GRUB."

# TTIME=`expr $STOP - $START`
# echo ""
# echo "*************************************************"
# echo "* Restoration Complete! *"
# echo "*************************************************"
# echo "Restoration took $TTIME seconds"
#
#
# Should I skip restore and use tar?
