After an excellent two days of troubleshooting and reinstalling ubuntu a couple of times I am looking for a way to save me time the next time I break my ubuntu installation.
I can read a lot online, but I am really looking for confirmation if I have the right idea in mind.
I have one disk of 1TB, divided in the following partions
- swap 32GB
- / 30GB
- /boot 500MB
- /boot/efi 1GB
My idea/hope was, that I can focus on /. If my hardware would start to fail, I have all relevant data backed up in online things. So I am not worried about "loosing data". I am worried about the time I loose to reinstall / configure everything again. So in case of hardware failure, I will accept the price to pay: replace hardware, install everything. Never happened before for me, fingers crossed ;-).
So, I want to create backups of / on a regular basis, so that if I do something stupid (like sudo apt install something which causes to fail the boot), I can restore the last backup for / and be up and running again. That backup is preferably as small as possible.
I want to create (and restore if needed) these backups using dd from ubuntu live (running on thumb drive). The backup will be a disk image of the / partition only. I will not touch any other partition.
Is this possible? Will this approach work? I know I can simply try, but I just spend two days reinstalling ubuntu, kind of hoping to not have to do it again :)
