Linux DD Disk Copy, Clone, Backup to image file
Hard Disk Clone
The following command can copy all the content from /dev/sda to /dev/sdb:
dd if=/dev/sda of=/dev/sdb
The following command will create an image file "disk1.img" in your user's directory from /dev/sda:
dd if=/dev/sda of=~/disk1.img
Since you have created an image file, you can compress it with "gzip" or "bzip2":
gzip disk1.img #generates disk1.img.gz or
bzip2 disk1.img #generates disk1.img.bz2
You can save much storage space with compression. But it will take very long time.
Partition Clone
For example, if you want to create an image file from the first partition of /dev/sda, use "dd" like this:
dd if=/dev/sda1 of=~/disk2.img
Also, you can compress the image file:
gzip disk2.img
You can copy a partition to another partition completely. For example:
dd if=/dev/sda1 of=/dev/sdb5
Restoring from an Image File
Restore the whole hard disk from the image file "disk1.img":
dd if=disk1.img of=/dev/sda
Restore the first partition of /dev/sda from the image file "disk2.img":
dd if=disk2.img of=/dev/sda1
The following command can copy all the content from /dev/sda to /dev/sdb:
dd if=/dev/sda of=/dev/sdb

dd if=/dev/sda of=~/disk1.img
