Which of the following implements this backup strategy?
Click on the arrows to vote for the correct answer
A. B. C. D.A.
The grandfather-father-son backup strategy is a backup rotation policy that uses multiple sets of tapes to ensure that data is backed up regularly and that backups from different points in time are retained for longer periods.
The "grandfather" tapes are the oldest backup sets, usually created weekly and kept for a longer period. The "father" tapes are created daily and kept for a shorter period, and the "son" tapes are created more frequently, often hourly or even more frequently, and kept for a very short period.
Option A: Assign a different set of tapes for daily, weekly, and monthly backups - This option implements the grandfather-father-son backup strategy by using different sets of tapes for different backup frequencies. This is a correct option.
Option B: Use a different set of tapes for every two, four, and eight days - This option does not implement the grandfather-father-son backup strategy as it does not include weekly and daily backups.
Option C: Designate a different set of tapes for odd-day and even-day backups - This option does not implement the grandfather-father-son backup strategy as it does not include weekly and daily backups.
Option D: Use a queue to rotate tapes based on the age and usage of the tape - This option does not implement the grandfather-father-son backup strategy as it does not include different sets of tapes for different backup frequencies.
Therefore, the correct answer is Option A: Assign a different set of tapes for daily, weekly, and monthly backups.
