The correct answer is scrubbing, which is a critical job in the Data Deduplication process. Scrubbing is designed to maintain the integrity of the deduplicated data by performing checksum validation and ensuring metadata consistency. Through this process, the system checks that the existing deduplicated data blocks are intact and that their associated metadata remains accurate. This is essential for preventing data corruption and ensuring that the storage optimization provided by deduplication does not compromise data reliability.

Other processes like deduplication job and garbage collection serve different purposes. The deduplication job primarily focuses on identifying and eliminating duplicate data to save storage space, while garbage collection is responsible for reclaiming space from deleted data blocks that are no longer needed. The repair job, on the other hand, is typically utilized to address issues or corruption found within data but does not specifically focus on periodic validation and consistency checking as scrubbing does. Thus, scrubbing is the designated job for ensuring the robustness of the stored data after deduplication.
