What is the purpose of backups in deployment planning?

• A. Improve system performance during peak loads
• B. Ensure data consistency during transactions
• C. Enable data recovery after loss or corruption
• D. Replace hardware during upgrade

Answer: (C)

Backups serve as a safety net that makes data recoverable after loss, corruption, or a disaster. In deployment planning, the goal is to be able to restore systems to a known good state with as little data loss as possible, which is the core reason for having backups. This ensures business continuity and minimizes downtime when something goes wrong, such as hardware failure, user error, or malware. Backups are not primarily about boosting performance during peak loads, nor about swapping out hardware during upgrades. They also aren’t what keeps transactions perfectly correct in real time; that relies on proper database mechanisms like atomicity and logging to maintain data integrity as operations occur. A solid backup strategy is often planned with recovery point objectives (RPO) and recovery time objectives (RTO) in mind, and includes different backup types and tested restore procedures to ensure reliable recovery.
