backup systems
Secondary operational reserves
Backup systems are secondary or redundant mechanisms designed to take over when primary systems fail.
The term applies across domains: a hospital's backup power generator, a spacecraft's backup navigation computer, or backup files stored separately from originals.
In computing, backup systems typically involve copying data to separate storage locations to prevent loss.
The backup systems kicked in when the main server crashed.
The emphasis is always on redundancy and reliability—having something ready when the first option fails.
