[olug] Backups??

[jay at reboottheuser.com]

Here's a simple example script, so you end up with individual files
under /mnt/backup/DATE_HOSTNAME/directory.tar.bz2


#!/bin/bash

DATE=`date +%m%d%y`
SYS=`uname -n`
BASE_DIR=/mnt/backup
BACKUP_DIR="${DATE}_${SYS}"
DEV=/dev/sda1

#make drive mount dir if needed
if [ ! -d /mnt/backup ] ; then
    mkdir ${BASE_DIR}
fi

#mount backup drive
/bin/mount ${DEV} ${BASE_DIR}

#check to see if it was mounted
CHECK_MOUNT=`/bin/mount | grep ${DEV}`

#if it was mounted then proceed with backup
if [ "${CHECK_MOUNT}" != "" ]; then

#make the timestamped backup directory
cd ${BASE_DIR}
mkdir ${BACKUP_DIR}

#make a backup listing of your partition layout
/sbin/fdisk -l > ${BASE_DIR}/${BACKUP_DIR}/fdisk_list

#start main backups
BACKUP_LIST="etc boot root home var "
cd /
for i in ${BACKUP_LIST}
do
         echo "tar cvfj ${BASE_DIR}/${BACKUP_DIR}/${i}.tar.bz2 ${i}"
         tar cvfj ${BASE_DIR}/${BACKUP_DIR}/${i}.tar.bz2 ${i}
done

#do extra backups
cd /usr
BACKUP_LIST="local"
for i in ${BACKUP_LIST}
do
         echo "tar cvfj ${BASE_DIR}/${BACKUP_DIR}/${i}.tar.bz2 ${i}"
         tar cvfj ${BASE_DIR}/${BACKUP_DIR}/${i}.tar.bz2 ${i}
done

#unmount drive
/bin/umount ${DEV}

else
   echo "Backup drive ${DEV} unable to mount on ${BASE_DIR}"
fi
