How to create ghost image of hard disk for free?
If 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 ofLinux.
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 havean OS installed in it.
Boot from Ubuntu Live CD/DVD. Now mount the hard disk youwant 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.i mg count=0 bs=512
or
[root@localhost ~]#dd if=/dev/sda of=/mnt/ partitiontable.i mg count=0 bs=1024
Now while restoring first restore partition table on new hard disk
[root@localhost ~]#dd if=/mnt/ partitiontable.i mg of=/dev/sda count=0 bs=512
or
[root@localhost ~]#dd if=/mnt/ partitiontable.i mg 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 meansif 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.
