Which statement best describes the purpose of backups in data management?

• A. to provide additional copies for sharing
• B. to prevent any data from ever being lost
• C. to recover from data loss events by restoring original data
• D. to replace the original data with backups

Answer: (C)

Backups exist to enable recovery after data loss by restoring the original data. They are copies kept apart from the live system so you can bring information back to its state before an incident—such as hardware failure, accidental deletion, corruption, or malware. The essential idea is restoration: you use the backup to reconstruct the usable data and get systems back online. This differs from simply trying to prevent loss or from replacing the original data with a backup. A backup isn’t a guarantee that nothing will be lost, and restoring from a backup does not overwrite the current data unless that’s the chosen recovery action. Backup strategies also consider how recently you need to recover (recovery point) and how quickly you must be up again (recovery time), and they require regular testing to ensure restores work when needed.
