Data Permanence refers to the longevity of data, ensuring it remains accessible and unaltered over time. This concept is crucial in the digital age, where information is often stored electronically. Techniques to ensure data permanence include regular backups, migration to new storage formats as old ones become obsolete, and the use of durable storage mediums. [[Data Ownership]] plays a pivotal role in data permanence, as it defines who has the authority to decide on these preservation methods.
