Explanation
To achieve quick restores while minimizing backup media usage, Differential (A) and Synthetic Full (B) backups are the best combination. A differential backup stores all changes since the last full backup, requiring only two sets for a restore (the last full + the latest differential)-making recovery faster than incremental. A synthetic full backup is assembled from existing full and incremental backups without re-reading the source data, providing full-backup restore speed without the storage overhead of repeatedly writing a complete full backup from scratch. Full backups (D) alone use the most media. Incremental (E) uses less media but requires restoring the full backup plus every incremental in sequence, making recovery slow. Archive (C) and open file (F) are not primary backup strategies for this use case.
