My Ubuntu set-up is quite complex and it requires few hours of installing software, changing bash configuration and creating a lot of symlinks. Since I often experiment with my system, it tends to get broken and I need to spend few hours configuring everything again.

  1. Is it possible to make copy of existing, working installation of Ubuntu, with everything configured, and in case of system failure or other issue, redeploy it on the same HDD/SSD/partition?
  2. Is the above possible with another partition, of new size and possibly on another device/HDD/SSD?

I hear about Clonezilla, but I am not sure it does what I described and I am not sure how to test if copy it creates works well.

  • The first is certainly possible, CloneZilla and Fog both do it. The second is bit more tricky. – muru Aug 5 '14 at 20:31

You could simply use dd to dump your partition into a file, like so:

sudo dd if=/dev/sda1 of=dump.img

Then you can easily restore it by running the following command from a live DVD / USB stick:

sudo dd if=dump.img of=/dev/sda1

Replace /dev/sda1 with your root partition. Obviously, you will need to place the dump file to another partition.


Another method would be to create a duplicate partition. Use any partitioning tool (e.g. GParted) to create a partition the same size as your original, then use dd to clone your partition:

sudo dd if=/dev/sda1 of=/dev/sda2

Do the inverse to restore, using a live DVD / USB stick.

  • Where will that dump.img file get stored? Can I store it in one of NTFS partitions? – Tejesh Raut Feb 29 '16 at 18:59

    It will be stored in your current working directory, of course. And sure you can use any partition as long as it can handle files as large as your dump. – kraxor Mar 1 '16 at 12:39

Use Remastersys. It will let you create an installable LiveCD based on your current setup. There's a great guide on how to install and use it here in the Ubuntu forums. The guide is for Karmic, but I've read that the app works in 14.04 as well. OBI seems like it would be able to do what you'd want as well.

  • The link you provided to Remastersys indicates that it has been taken down by the developer. – 24601 Nov 3 '14 at 11:16
  • Yes, but the application still works as expected. – amanthethy Nov 3 '14 at 14:59
  • ^^As indicated by the links I provided. – amanthethy Nov 3 '14 at 17:57

You could utilize ubuntu landscape, and create a profile for your computer which will handle all the custom software installations and what have you.
