You’d be surprised how often critical tools don’t have backups.
More than once I’ve been to sites where the software needed to service a critical piece of equipment only existed on a single 15+ year old banged up laptop, or a 40+ year old PLC handling a critical part of a production line couldn’t be turned off because there was a risk that it wouldn’t be able to turn back on, and it was EOL’ed over a decade ago but they still hadn’t ported the program to a newer platform.
