In the GFS backup scheme, what do Grandfather, Father, and Son refer to?

• A. Monthly, weekly, and daily backups respectively
• B. Daily, weekly, and monthly backups respectively
• C. Offsite, onsite, and cloud backups
• D. Primary, secondary, and tertiary backups

Answer: (A)

The idea being tested is how the Grandfather-Father-Son scheme manages backups over different time horizons using three levels of retention. In this naming, the oldest level is Grandfather, the middle is Father, and the newest is Son. Grandfather refers to monthly backups, Father to weekly backups, and Son to daily backups. This arrangement keeps a long-term archive (monthly), a mid-term history (weekly), and a recent set for quick restores (daily). The word order in the statement matches this: Grandfather = monthly, Father = weekly, Son = daily, which is why the option saying Monthly, weekly, and daily backups respectively is the best fit. Other choices mix up the timeframes or refer to locations or redundancy instead of the time-based levels used in GFS, so they don’t align with how the naming is intended.
