Explanation: Data Segment Processing (DSP) on PowerProtect DD offloads deduplication functions to the backup host, where segmenting, fingerprinting, and sending only unique data references improve backup efficiency and reduce storage footprint. When Distributed Segment Processing (DSP) is enabled on a PowerProtect DD appliance, key functions such as segmenting, fingerprinting, and sending the fingerprints are performed on the backup host. DSP offloads some processing tasks to the backup host, allowing the appliance to focus on storage efficiency and performance. Here's how each function works with DSP:
* Segmenting: The backup host divides data into smaller segments.
* Fingerprinting: Each segment is hashed (fingerprinted) to identify unique data segments.
* Sending the fingerprints: Only the fingerprints are sent to the DD appliance, allowing it to verify deduplication without transferring the full data. This process minimizes bandwidth and optimizes backup efficiency.
