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.

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.
