How does SnapDiff determine which files have changed?

The correct answer is D. It runs an incremental backup of the files that were reported as changed by the filer. Using the snapdiff option with the incremental command streamlines the incremental backup process. The command runs an incremental backup of the files that were reported as changed by NetApp instead of scanning all of the volume for changed files
