What are the BEST backup methods to use when a quick restore is desired while minimizing backup media usage?

• A. Full backups and Incremental backups
• B. Differential and Synthetic full backups
• C. Mirroring and Cloud backups
• D. Snapshot backups and Local backups

Answer: (B)

The most effective backup methods for achieving a quick restore while minimizing backup media usage are differential and synthetic full backups. Differential backups capture all changes made since the last full backup, which allows for a faster restore process compared to incremental backups, as only the last full and the most recent differential backup need to be restored. This significantly reduces the number of backup sets required for a complete recovery, as opposed to using full and incremental backups, which require restoring each incremental backup in the correct order. Synthetic full backups enhance this process by creating a full backup from previous backups without needing to revert to the original data source. They combine data from existing full and incremental backups to create a new full backup, minimizing the time required to restore data, while also conserving storage space. This combination effectively meets the dual requirements of quick restoration and reduced media usage, making it an optimal choice for backup strategy.
