Why is backing up important?

• A. To prevent or reduce data loss
• B. To prevent hardware failures
• C. To increase processing power
• D. To reduce network traffic

Answer: (B)

Backing up data means making extra copies of important files so you can recover them if something goes wrong. Data loss can happen in many ways—hardware failures, accidental deletion, file corruption, malware, or disasters. A backup gives you a restore point, so you can recover the original data and get back to work with minimal downtime and loss. Backups don’t stop hardware from failing, but they reduce the impact by letting you restore data after a failure. Good practice includes multiple copies, on different media, with at least one copy stored off-site or in the cloud, and regularly testing that you can restore successfully.
