What is a Backup?

What is a Backup?

• A. A duplicate copy of data made for archiving purposes or for protecting against damage or loss.
• B. An acronym for business as usual.
• C. A wireless protocol for short-range data.
• D. A vulnerability in programming.

Answer: (A)

Backups are duplicate copies of data created to protect information from loss, damage, or corruption and to support recovery when something goes wrong. They’re kept separately from the live data so you can restore systems and files to a known good state after incidents like hardware failures, accidental deletions, or ransomware. Backups also serve archival purposes, preserving historical data as needed. For effective data protection, backups should be secured (encryption, access controls) and tested regularly to ensure you can restore from them. The other options describe something entirely different—an acronym for business as usual, a short-range wireless protocol, or a programming vulnerability—so they don’t define what a backup is.
