How does deduplication improve backup efficiency?

Data deduplication helps improve backup storage efficiency and reduce overall costs by identifying and eliminating duplicate copies of data within a storage system. This process involves only storing unique data once and creating references to that unique data when it appears elsewhere. By reducing the amount of redundant data being stored, data deduplication maximizes storage capacity utilization, decreases the size of backups, and speeds up data retrieval. As a result, organizations can store more data in less space, reduce the need for additional storage hardware, and save on costs associated with backup storage, management, and bandwidth usage.
