The ultimate sysadmin nightmare in four panels! First guy panics: "Server has crashed. Where is backup?" Second guy's face says it all when he realizes the backup is... wait for it... "On the server."
It's that gut-wrenching moment when you discover your disaster recovery plan has a single point of failure. Like keeping your only house key inside your locked house. The digital equivalent of storing your umbrella exclusively for use during floods... in your basement.
