h1. CloneZilla Disaster Recovery

h2. Start CloneZilla

h3. Requirements

To install such a system you will need the following:

* The supplied clonezilla-live-1.2.8-23-i686 CD **or**

* Download this or a newer version of the clonezilla-live CD and burn it on an empty CDROM (the .iso can be found here: http://clonezilla.org/downloads/stable/iso-zip-files.php)

* a bootable CDROM-drive

h3. Preliminary Note

In this tutorial I use a virtual machine to backup and restore. It is assumed that the first harddrive (sda) is the system-drive and the second harddrive is the backup-drive (e.g. USB-HDD). These settings might differ for you, so you have to replace them where appropriate.

h3. Start CloneZilla

Boot from your CloneZille-Live CD. Press @<ENTER>@ at the boot prompt:

Select the language you prefer, I stick with English

Select the keymap for your keyboard, I stick with Standard-US, if you want to change the keyboard-layout select the first option @Select keymap from arch list@.

!{width: 500}clonezilla3.png!

@Start CloneZilla@ obviously

!{width: 500}clonezilla4.png!

Since we want to work with images -> @device image@

!{width: 500}clonezilla5.png!

the fastest way is to use a local drive (e.g. USB-HDD)

!{width: 500}clonezilla6.png!

if your USB-device is not yet connected, connect it and wait a few seconds before you continue

!{width: 500}clonezilla7.png!

select the drive you want to backup to or to restore from. Don't get confused, CloneZilla want's to know the target before the source when saving an image!

!{width: 500}clonezilla8.png!

select the directory where the image should reside. Choosing the @root@ is always a safe decision.

!{width: 500}clonezilla09.png!

now we see the filesystem seen by CloneZilla. The image will reside always in @/home/partimag@. The drive to be saved or to be restored must not be part of the filesystem.

!{width: 500}clonezilla10.png!

by using @Beginner@ mode the safe default values are automatically chosen. If you have a big multi-core machine you might choose @Expert@ and leave everything default but set the compression method to @pigz@

h2. Backup (make image of system)

choose @savedisk@

!{width: 500}clonezilla12save.png!

give the image a strong name, date and system-name are a good starting point

!{width: 500}clonezilla13save.png!

choose the drive to be imaged

!{width: 500}clonezilla14save.png!

if you want to be sure that your image is working, stick with @yes, check the saved image@

!{width: 500}clonezilla15save.png!

if you want to know what command-sequence you would have had to enter manually, here it is.

!{width: 500}clonezilla16save.png!

now we get a list of all partitions found on the source-drive

!{width: 500}clonezilla17save.png!

let's watch the progress of the imageing process

!{width: 500}clonezilla18save.png!

let's watch the progress of the image check

!{width: 500}clonezilla19save.png!

check if the image could be read back successfully.

!{width: 500}clonezilla20save.png!

let's poweroff the machine gracefully

!{width: 500}clonezilla21save.png!

remove the CloneZilla-Live-CD from the drive

!{width: 500}clonezilla22save.png!

h2. Restore

choose @restoredisk@

!{width: 500}clonezilla12rest.png!

choose the image to be restored

!{width: 500}clonezilla13rest.png!

choose the restore target drive

!{width: 500}clonezilla14rest.png!

if you want to know what command-sequence you would have had to enter manually, here it is.

!{width: 500}clonezilla15rest.png!

now we get a reminder, that all data on the target drive will be lost

!{width: 500}clonezilla16rest.png!

this is the last chance to change your mind

!{width: 500}clonezilla17rest.png!

let's watch the progress of the restore process

!{width: 500}clonezilla18rest.png!

check if the image could be read back successfully

!{width: 500}clonezilla19rest.png!

let's poweroff the machine gracefully

!{width: 500}clonezilla20rest.png!

remove the CloneZilla-Live-CD from the drive
