A backup plan
Meaning
A secondary strategy or course of action prepared in case the primary one fails or becomes impossible.
Origin
The phrase "backup plan" rose to prominence in the 20th century, particularly as the digital age dawned and the concept of "backing up" data became critical. Imagine the early days of computing, where a single system crash could wipe out days or weeks of work. To prevent this catastrophe, engineers developed the practice of creating "backups"—duplicate copies of files and systems, ready to be deployed if the original failed. This literal act of preparing a reserve quickly extended into our everyday language. The idea of having a secondary, ready-to-go option, mirroring the digital world's need for redundancy, solidified the phrase "a backup plan" as a punchy, modern way to describe any prepared alternative, ensuring you're never left completely stranded.
Examples
