Deduplication is the process of identifying and removing duplicate or redundant data within a database or storage system. This technique helps to optimize storage space and improve data management by eliminating unnecessary copies of the same information. By identifying and eliminating duplicate data, deduplication reduces storage costs and improves system performance. It is a crucial aspect of data management, especially in large organizations where data duplication can lead to inefficiencies and increased storage costs. Deduplication not only saves storage space but also ensures data integrity and accuracy, making it an essential tool for efficient data management.
