Which type of backup will include only those files that have changed since the most recent Full backup?

A.
Full

B.
Differential

C.
Incremental

D.
Binary

Explanation:
Answer B is correct; differential backups will only archive those files that have changed since the most recent full backup.

Incorrect Answers and Explanations: A, C, and D: Answers A, C, and D are incorrect. A full backup would archive all files regardless of whether they had changed or not. An incremental backup will only archive those files that have changed since the last incremental or full backup. Binary backups are used for forensics and incident response purposes and will backup everything on the entire disk, both allocated and unallocated space.
