👉 A reserve or substitute.
Alright class, settle down and letās take a look, At this word ābackup,ā a little bit of hook! The dictionary tells us, itās true you see, āA reserve or substituteā ā that's the key! Think of it like this, a lovely little rhyme, If something goes wrong, itās there in good time. Like having a backup plan, when things don't go as planned, Or saving your files, across the digital land! It means an extra copy, safe and sound you know, Just in case the original starts to slow. So ābackupā isnāt just one thing, itās a safeguard bright, A second chance, shining with all its light! Does that make sense? Any questions for me?
