Data Deduplication Overview | Microsoft Learn
https://learn.microsoft.com/en-us/windows-server/storage/data-deduplication/overview
Data Deduplication , often called Dedup for short, is a feature that can help reduce the impact of redundant data on storage costs. When enabled, Data Deduplication optimizes free space on a volume by examining the data on the volume by looking for duplicated portions on the volume. Duplicated portions of the volume's dataset are stored once and are (optionally) compressed for additional savings. Data Deduplication optimizes redundancies without compromising data fidelity or integrity. More information about how Data Deduplication works can be found in the 'How does Data Deduplication work?' section of the Understanding Data Deduplication page.
What is data deduplication? - IBM
https://www.ibm.com/think/topics/data-deduplication
What is data deduplication? Data deduplication is a streamlining process in which redundant data is reduced by eliminating extra copies of the same information . The goal of data deduplication, or “dedupe” as it’s commonly shortened, is to lessen an organization’s ongoing storage needs.

Feb 20, 2026 · Data deduplication is the process of identifying and eliminating duplicate copies of data to reduce storage, bandwidth, and processing waste while preserving logical correctness.
What are the Types of Data Deduplication? | IBM
https://www.ibm.com/think/topics/data-deduplication-types
Although many organizations make use of data deduplication techniques (or “dedupe”) as part of their data management system, not nearly as many truly understand what the deduplication process is and what it’s intended to do. So, let’s demystify dedupe and explain how data deduplication works.
What is Data Deduplication? - Data Deduplication Explained - AWS
https://aws.amazon.com/what-is/data-deduplication/
Data deduplication is the process of finding and removing copies of the same data to avoid redundancy and errors . After data deduplication, only one instance of the data exists.
Understanding Data Deduplication | Microsoft Learn
https://learn.microsoft.com/en-us/windows-server/storage/data-deduplication/understand
Feb 18, 2022 · Data Deduplication uses a post-processing strategy to optimize and maintain a volume's space efficiency. The Optimization job deduplicates by chunking data on a volume per the volume policy settings, (optionally) compressing those chunks, and storing chunks uniquely in the chunk store.
