Creating Cloning or Backup ISO Image of System/Server

There are two ways to create a Backup/Clone ISO. Interactive and command line.

Interactive Bacup/Clone ISO Image

After installing Mondo, Run “mondoarchive” command as “root” user. Then follow screenshots that shows how to create an ISO based backup media of your full system.

If you’ve selected default backup path, you will see an ISO image under “/var/cache/mondo/“, that you can burnt into a CD/DVD for later restore.

Command Line Bacup/Clone ISO Image

To create a one line full backup ISO with name “mybackup”v run:

mondoarchive -O -p mybackup -i -d /var/cache/mondo -s 4480m

this will create a file named “mybackup-1.iso” at the path “/var/cache/mondo”

Shedule a daily backup (CRON JOB)

1. Use ‘at’ to run your usual mondoarchive command

# at now + 5 min

#  mondoarchive -O -p mybackup -i -d /var/cache/mondo -s 4480m

# <CTRL>-d

2. Grab the script generated by ‘at’ and make a copy of it

grep mondo /var/spool/at/* 
cp /var/spool/at/<file-from-grep> /root/mondo-cronscript

3. Edit that script to use ‘<your mondoarchive command>’

# vi /root/mondo-cronscript

4. at the end of the script add a new line with the mondoarchive command:

mondoarchive -O -p mybackup -i -d /var/cache/mondo -s 4480m

5. Run that script from your crontab (the egample is a "working" daily task, monday to friday at 00:00)

# crontab -e

0 0 * * 1-5 /root/mondo-cronscript

Restore

To restore burn the ISO to a DVD (or mount it if using virtualization) and start the server. At the prompt write “nuke” and it will restore the whole disk (re-image).

If restoring to different machine/VM it will have different MAC address. It need to change the MAC address of the eth0 interface to the new one in order the interface to be enabled.

MAC address change after restore

ifconfig -a (check the MAC address)

vi /etc/sysconfig/network-scripts/ifcfg-eth0 (edit the MAC address adding the new one)

service network stop

service network start

ifconfig -a (check it eth0 is up)

if not then try “ifup eth0”
