How to make a disk image and restore from it later?

In windows back is very easy with Norton ghost. Run it and forget it, What is the same type of software for backing up the Ubuntu system? I tried DUP back up but it failed to restore when I really needed it.

Can you suggest anything regarding system back up for Linux systems?

To create an image of a disk is very easy. Let's say you want to create an image of sda in /media/my_dev_sdb:

sudo dd if=/dev/sda of=/media/my_dev_sdb/disk_sda.img.

If it's your main disk, then it's wise to boot a live session and do it from there instead.

What is CloneZilla?

You're probably familiar with the popular proprietary commercial package Norton Ghost®. The problem with these kind of software packages is that it takes a lot of time to massively clone systems to many computers. You've probably also heard of Symantec's solution to this problem, Symantec Ghost Corporate Edition® with multicasting. Well, now there is an OpenSource clone system (OCS) solution called Clonezilla with unicasting and multicasting!

Clonezilla, based on DRBL, Partclone and udpcast, allows you to do bare metal backup and recovery. Two types of Clonezilla are available, Clonezilla live and Clonezilla SE (server edition). Clonezilla live is suitable for single machine backup and restore. While Clonezilla SE is for massive deployment, it can clone many (40 plus!) computers simultaneously. Clonezilla saves and restores only used blocks in the harddisk. This increases the clone efficiency. At the NCHC's Classroom C, Clonezilla SE was used to clone 41 computers simultaneously. It took only about 10 minutes to clone a 5.6 GBytes system image to all 41 computers via multicasting!
