What is a typical backup retention policy described as rotating daily, weekly, and monthly backups?

• A. Keep backups indefinitely without rotation
• B. Rotate yearly backups only
• C. Rotate daily, weekly, monthly backups and keep long-term backups
• D. Keep only the most recent backup

Answer: (C)

A backup retention policy that rotates daily, weekly, and monthly backups uses multiple backup levels to balance quick recovery of current data with long-term archival. Daily backups capture the most recent state and are kept for a short period, allowing fast restoration from yesterday or today. Weekly backups provide a longer window for mid-term restores, protecting against issues that aren’t detected immediately. Monthly backups are kept even longer, enabling restores from months or years back for compliance or historical needs. Rotating means you periodically replace older backups with newer ones, so you maintain a manageable set at each level rather than unlimited copies.

This approach is why the best choice describes rotating daily, weekly, monthly backups and retaining long-term backups. Options that suggest keeping backups indefinitely, rotating only yearly, or keeping only the most recent backup do not provide the layered history needed for flexible restoration across different time points.
