Which term describes the practice of making duplicates of data to safeguard against loss?

• A. Backing up
• B. Archiving
• C. Cloud computing
• D. Online storage

Answer: (A)

Backing up data means creating duplicates of your files and systems so you can restore them after loss, damage, or corruption. This practice ensures you have a recent copy available if something goes wrong, often with multiple copies on different media or locations (the 3-2-1 rule). Archiving focuses on long-term retention of older or infrequently accessed data, not on rapid recovery. Cloud computing is a broader model for delivering resources online, while online storage is simply storing data on remote servers; these can support backups but aren’t the act of duplicating data for protection itself. So the correct term is backing up.
