How do I create a dd image of multiple filesystems in Xubuntu 12.04?

  • 772

I have four filesystems with various sample files on them that I want to combine into a single image. How would I do this using dd? Should I be using something else other than dd? Thanks.

    While you can either have the entire disk be imaged, or one partition, it is impossible to use dd to put multiple partitions (selectively) in one file. It would require reworking the partition table of the image. You can, however, selectively copy multiple partitions to separate files. Let's copy /dev/sda1 and /dev/sda3 below:

    sudo dd if=/dev/sda1 of=/media/HARDDISK/sda1.img

    sudo dd if=/dev/sda3 of=/media/HARDDISK/sda3.img

    This creates two files in the directory of your choice (see second argument). Be careful not to get the if and of confused as you can destroy data if you make a mistake.
