Which is a function of Data Deduplication in Windows Server?

• A. Garbage Collection
• B. Data Scrubbing
• C. Defragmenting
• D. Cache Clearing

Answer: (B)

Data Deduplication includes maintenance tasks that go beyond simply saving space. One function is scrubbing, which ensures integrity for deduplicated data by reading the blocks, validating their checksums, and repairing any corruption found. This helps detect and fix issues that could affect reliability of the deduplicated data. Garbage collection is another dedup task that reclaims space by removing unreferenced deduplicated chunks, but it focuses on space reclamation rather than integrity checks. Defragmenting and cache clearing aren’t functions of Data Deduplication. So, scrubbing is the specific function described.
