I am guessing even a backup, clean load of the OS and restore of data will lose the whole profile. This will cause us to change a fair amount of procedures as the chrome profile, containing everyone's passwords is a big deal. Since we deal with older people where their most important thing is the password to log in to accounts, is EVERYTHING to them. If we do a job and lose this information, in their mind(which is all that matters) we lost all of their stuff.
We will need to experiment to see if we can we use a program like webpassview on an unbootable system to pull the passwords out of the old profile. This would be an okay solution, I suspect it will not work on an unbootable system
