Which term describes the process of removing data that is no longer needed?

The process of removing data that is no longer needed is best described as data destruction. This term specifically refers to the methods and practices used to permanently eliminate data from storage devices so that it cannot be retrieved or reconstructed. This is particularly important for sensitive or confidential information, as improper disposal of data can lead to potential security breaches or unauthorized access.

In contrast, other terms like data archival, data storage, and data sharing have different meanings. Data archival refers to the process of moving data that is not actively used to a separate storage location for long-term retention, usually for compliance or historical purposes. Data storage involves maintaining data in various formats and locations to ensure it is readily accessible for future use. Data sharing concerns the distribution of data among different users or systems, focusing on making data available rather than removing it. Therefore, the concept of data destruction is specifically aligned with the complete removal of data that is no longer deemed necessary.
