The correct answer is C. Incremental. Incremental backups only capture data changed since the last backup of any type, making each backup window as short as possible on weekdays.
Question
A cloud administrator is choosing a backup schedule for a new application platform that creates many small files. The backup process impacts the performance of the application, and backup times should be minimized during weekdays. Which of the following backup types BEST meets the weekday requirements?
Options
- ADatabase dump
- BDifferential
- CIncremental
- DFull

Why each option
Incremental backups only capture data changed since the last backup of any type, making each backup window as short as possible on weekdays.
A database dump is a logical export method specific to databases, not a general-purpose backup schedule type that addresses backup window duration.
Differential backups capture all changes since the last full backup, so the backup set grows larger each day of the week, increasing - not minimizing - weekday backup times.
Incremental backups record only the blocks or files changed since the most recent backup run, regardless of whether that prior run was full or incremental. This produces the smallest backup sets and the shortest backup windows, directly satisfying the weekday performance requirement. Each successive weekday backup builds on the previous incremental, not on the full, so backup size stays minimal.
A full backup copies all data every time it runs, producing the largest possible backup window and the highest performance impact on weekdays.
