Root Explanation
Backup → It is formed from "back" (from Old English "bæc", meaning the rear or behind) and "up" (meaning to a higher position or level). The word "backup" refers to a copy or support that is positioned behind or in reserve.
Memory Tip
Think of something that is 'behind' ('back') and 'higher' ('up') — a backup is like a support that is ready to step in when needed.
