Digital preservation is the process of maintaining and protecting digital content to ensure its long-term accessibility and usability. This involves strategies and actions that guard against technological obsolescence, data corruption, and loss, so that digital information - such as documents, images, and databases - remains available and understandable in the future. Techniques may include regular data backups, format migration, and the use of standardized file types. Digital preservation is essential for organizations, libraries, and individuals who need to safeguard valuable digital assets over decades, regardless of changes in software or hardware.
