B. It scans the file system for changed blocks.
C. It compares the TOC stored in the TSM database.
D. It runs an incremental backup of the files that were reported as changed by the filer.
Correct Answer: D
Explanation/Reference:
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
