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.
- 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?
- 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.
