To minimize the backup window after month-end while ensuring fast restoration, which backup type should be scheduled?

• A. Synthetic full
• B. Incremental
• C. Differential
• D. Full

Answer: (A)

Synthetic full backups minimize the backup window while keeping restoration fast by creating a complete backup image on the storage system without re-reading all data from the production environment. The backup server uses existing full and incremental backups to assemble a new full backup on disk, so the network and I/O load during the backup window are reduced. This means you can finish the month-end backup quickly even as data volumes are large. When restoring, you have a current full backup readily available on the repository, and you can apply only the most recent changes as needed, which makes the restore faster than rebuilding from many incremental pieces. In contrast, a full backup would require transferring all data again and would take longer; incremental backups, while quick to run, can slow restoration since they must be combined in sequence, and differential backups grow larger over time, increasing both backup size and recovery time.
