Deduplication is a data management process that eliminates duplicate copies of data to save storage space and improve efficiency. This technique is commonly used in data backup and storage systems, where multiple copies of the same file can take up unnecessary space. By identifying and removing duplicates, organizations can optimize their storage resources. In addition to saving space, deduplication can enhance data transfer speeds and reduce bandwidth usage. It is often implemented in cloud storage services and data centers, where large volumes of data are handled. Overall, deduplication helps streamline data management and reduce costs associated with storage.
