====== Using disk images ======
You can use the command line to work with disk images and backups, without any extra software.

===== Create a hard disk image =====
<code bash>sudo dd if=/dev/hda1 of=/home/hda1.bin</code>

Or for a compressed disk image:
<code bash>sudo dd if=/dev/hda1 | gzip > /home/hda1.bin.gz</code>

===== Back up and restore the MBR =====
<code bash>sudo dd if=/dev/hda of=/home/hda.boot.mbr bs=512 count=1</code>

Restore MBR (from a Live CD)
<code bash>sudo dd if=/mnt/hda1/home/hda.boot.mbr of=/dev/hda bs=512 count=1</code>

===== Backup a drive to another drive =====
<code bash>sudo dd if=/dev/hda of=/dev/hdb conv=noerror,sync bs=4k</code>

===== Write an Ubuntu ISO to USB =====
Assuming your USB stick is /dev/sdb, don't use the partition (/dev/sdb1):
<code bash>sudo dd if=Ubuntu.iso of=/dev/sdb</code>
