Backup script

High-gain · 05-17-2007, 04:25 AM

Hi There

I wonder if anyone could help me with this back up script for 2007(official)

The script works ok, but would like to convert it so that I back up my whole

system, perhaps to the Hdd, then burn to a CD-r/CDVD-r.

As a newbie I am not really sure on what to back up, or what to exclude.

I have tried drakbackup, but does not really do it for me and seems to be

very flakey. It's probably me not using drakbackup properly, so would like

something really simple and easy to use.

Here is the script - hope someone can help. Thanks.

########################################################################

#!bin/bash

#create a compressed backup of all the directories specified and put the
#resulting file in a directory of your choice

#BACKUP_DIRS="$HOME /etc /var "
#BACKUP_FILENAME=sysback-`date '+%d-%B-%Y'`
#BACKUP_DEST_DIR="/backups/sysbkup"

#tar cvzf $BACKUP_DEST_DIR/$BACKUP_FILENAME.tar.gz $BACKUP_DIRS

###################################################################

#1.Use BACKUP_DIRS to specify the directories you WANT to include in the backup

#2.Use BACKUP_DEST_DIR to specify the DESTINATION directory to store the backup

What you backup depends a bit on your setup. The basic bersion above doesn't look too bad. You may want to add /root as well

Here's by copy to dvd portion from one of my backup scripts

Code:

echo "ISO production started....";date

mkisofs -r -R -J -l -o "$BACKUP_PATH/$BACKUP_FILENAME.iso" "$DEST.bz2"

echo "mkisofs completed ";date
echo

cdrecord dev=/dev/dvdwriter driveropts=burnfree -dao "$BACKUP_PATH/$BACKUP_FILENAME.iso"

echo "Removing ISO";date
echo

rm -f "$BACKUP_PATH/$BACKUP_FILENAME.iso"

You'll need to change some variable names if you want to use it

Thanks BillyMayDay for your help and also the quick reply.

If this script runs ok for me (I am sure it will) - then

what would be the best way to run this. i.e. will I have

to change any permissions? Do I put the media in the cdrom

and then execute?

Also would I need another script to restore the backup?

Silly questions I know, but am still at the early learning

center (kindergarden) Hi. Thanks again for your input.

Yes, you'll need media in the dvd drive (it's unlikely to fit on a cdrom)

wrt restoring, you probably don't want a script, but will want to get friendly with tar to restore

Great stuff Billmayday - many thanks for your input.

In this script I am thinking of excluding the following directories -

#proc
#mnt
#temp
#the backup directory

I wonder if there would be any more that need to be excluded?

Where and how would I write that in the script?

Also, when I restore via tar, will this script 'overwrite'
the current files.

Will have to get the books out on this backup stuff, but thanks
again for helping.
