The fallback you hope to never need but always check exists first.

means A source of help or a course of action you can turn to when things go wrong, especially a way to get relief or correction.

from From French recours, tracing back to Latin recursus — 'a running back' — built from re- ('back') plus currere ('to run'), the same root that gives us 'current' and 'course.' The idea is literally of running back to something for help, like retreating to a safe position you know is there.
