[LUGOS] Backup

[Saso Span]

Moja backup skripta:
/etc/cron.weekly/backup.cron

#!/bin/sh
# for FULL backups
# this backs up the important stuffs listed in ${lists} to ${BKPDIR}
# the lists *should* be in ${BKPDIR} and named <whatever>.lst
# the resulting backups will be <whatever>.<timestamp>.tgz
#
# notes:
# variables in CAPS are ok for you to set
# change the other variables if you know what you're doing
# you can get fancy in the lists... (think xargs *wink*)
# assumes /boot is usually unmounted, and has an /etc/fstab entry
# follow your security policy when setting perms on ${BKPDIR}
#

# DISCLAIMER: razamatan didn't write this if something goes wrong

mount /dev/hdc1 /mnt/backup
sleep 60s

BKPDIR=/mnt/backup/system       # where the backups go
BOOT=sys                        # list that has /boot
NUMBKPS=1                       # how many backups to keep

if [ ! -d ${BKPDIR} ] ; then
        echo ${BKPDIR} is not a valid directory or is non-existant
fi

lists=${BKPDIR}/*.lst
ext=tgz

for list in `ls ${lists}`; do
        type=`basename ${list} .lst`

        if [ ${type} = ${BOOT} ] ; then mount /boot ; fi
        cat ${list} | xargs tar zlcf \
                ${BKPDIR}/${type}.`date +%Y-%m-%d-%H%M`.${ext} >
/dev/null 2>&1
        if [ ${type} = ${BOOT} ] ; then umount /boot ; fi

        num=${NUMBKPS}
        for evict in `ls -t ${BKPDIR}/${type}.*.${ext}`; do
                if [ ${num} -le 0 ] ; then rm -f ${evict}
                else num=$((${num}-1)) ; fi
        done
done

umount /mnt/backup
hdparm -y /dev/hdc


Najprej mi požene in mounta moj stari hd, ter naredi backup v
/mnt/backup/system. Nato ugasne disk.
Za file list imam datoteko /mnt/backup/system/sys.lst

--exclude=/home/saso/download
/usr/local/portage
--exclude=/usr/local/portage/distfiles
/usr/src/linux/.config
/var/lib
--exclude=/var/lib/texmf
