If yes then you are the person who want to backup complete disk along with OS. So lets see how we can create hard disk image or ghost image or disk clone without using those highly priced ghost creating software.
Requirements:
Ubuntu Live CD/DVD, A hard disk with more capacity than the one you want to clone and some basic knowledge of Linux.
Procedure:
Linux
provides disk dumping feature, this feature can be used for creating
complete backup of any possible storage media. And we will use this
feature of Linux command shell to create ghost images. While writing
this tutorial I am assuming that you want to backup a hard disk which
already have an OS installed in it.
Boot from Ubuntu Live CD/DVD
Now mount the hard disk you want to take backup on /mnt folder
Now take backup using following commands,
[root@localhost~]dd if=/dev/sda1 of=/mnt/image.img
this will create complete image of hard disk partition sda1, next you must take backup of partition table,
[root@localhost~]#dd if=/dev/sda of=/mnt/partitiontable.img count=0 bs=512
or
[root@localhost~]#dd if=/dev/sda of=/mnt/partitiontable.img count=0 bs=1024
Now while restoring first restore partition table on new hard disk
[root@localhost~]#dd if=/mnt/partitiontable.img of=/dev/sda count=0 bs=512
or
[root@localhost~]#dd if=/mnt/partitiontable.img of=/dev/sda count=0 bs=1024
Finally restore ghost image,
[root@localhost~]#partprobe /dev/sda
[root@localhost~]#dd if=/mnt/image.img of=/dev/sda1
Now
please note that when you'll create ghost image no matter what amount
of data you have in disk your ghost disk will be of actual size of
source hard disk, that means if your source hard disk is 40GB in size
then your ghost hard disk will also be of 40GB. If you think above
tutorial was little geeky then even I don't take different view from
you, yes its really little geeky but believe me its not that difficult.
