Which option best describes the purpose of backups in relation to data loss?

• A. Backups are not related to data loss
• B. Backups should be created only after data loss occurs
• C. Backups serve as protection against damage or loss of original data
• D. Backups replace the original data

Answer: (C)

Backups are a protective measure that creates copies of important data so you can recover it if the original becomes damaged, corrupted, deleted, or lost. Because the restore relies on these copies, backups function as a safeguard against data loss—providing a way to return systems to a known good state without starting from scratch. This preventive role means backups should be made regularly and kept separate from the live data, ideally in secure off-site or offline storage so events like hardware failure or ransomware won't compromise both the original and its backup. Backups do not replace the original data; they are used to restore it. They are also not something you only create after data loss, since having current backups ready is what makes recovery possible. In short, the purpose of backups is to protect against damage or loss of the original data, enabling recovery to the last good state.
