I maintain a weekly updated backup of my whole hard disk with Kubuntu 14.04, thanks to Rsync. I rarely need to restore the back up, but today I did something nasty to my OS, too complex to try to fix it myself and I would like to restore the files of the back up blindly.
The problem is, I shrunk the main partition yesterday. If I restore everything, I am afraid I will overwrite some critical linux files containing information about the physical drive and the partition and it will make things worse.
What are the files I should avoid overwriting with those in the backup? I guess it must be something within the /dev folder, but which ones exactly?
