Thanks for the tips. I'm getting better;)
I've been making this backup script which
is nearly complete:
#!/bin/sh
#
# Russ' backup
#
# Warning: Do not run unless you understand every line of this script
#
# Copy everything (almost) from the system to a backup removeable hard-disk
# Assumptions:
# run in super-user mode
# the spare hard-disk has enough capacity
# the spare disk has been formatted to match the original
# in number and type of partitions
#
# The spare disk won't be bootable unless lilo is run separately,
# which i haven't got around to doing yet
# The /boot partition:
HDD_BOOT=hdc1
# The main root / partition:
HDD_MAIN=hdc3
# Mount /boot partition
if ! mount | grep -qs /dev/$HDD_BOOT
then
if ! mount -t ext2 /dev/$HDD_BOOT /mnt
then
echo "Removeable /dev/$HDD_BOOT not working"
exit 1
fi
fi
# Copy /boot partition
echo "Updating /boot"
if ! cp -auv /boot /mnt
then
echo "Failed to update /boot"
exit 1
fi
# Mount main partition
umount /mnt
if ! mount | grep -qs /dev/$HDD_MAIN
then
if ! mount -t ext2 /dev/$HDD_MAIN /mnt
then
echo "Removeable $HDD_MAIN not working"
exit 1
fi
fi
# Copy everything on main partition
# Strip some top level directories we don't want to copy
FILES=$( ls / | sed -e s/boot//g | sed -e s/cdrom//g | sed -e s/proc//g | sed -e
s/floppy//g | sed
-e s/mnt//g | sed -e s/dev//g)
# Note: I really want to copy some of these directories and their contents with
# any attributes preserved, but without copying the contents of the files
# (haven't figured out a command for that yet)
OPTS="-auv"
for i in $FILES
do
echo "Updating /$i"
if ! chroot / cp $OPTS $i /mnt
then
echo "Failed to update /$i"
exit 1
fi
done
echo "System backup successful"
exit 0
