Which of the following is NOT a key component of a digital preservation strategy?

A digital preservation strategy focuses on ensuring the long-term accessibility and usability of digital materials. Key components typically include format migration, which involves updating or converting files to current formats to avoid obsolescence; data integrity checks, which help maintain the accuracy and reliability of digital information over time; and regular backups, which are essential for safeguarding against data loss.

The creation of physical archives, while important in certain contexts, is not a key component of a digital preservation strategy specifically. This is because physical archives pertain to traditional, tangible objects and documents rather than digital assets. Digital preservation strategies emphasize digital methods and responses to the unique challenges that digital files present, rather than creating physical versions of digital content. Thus, while physical archives can complement broader preservation efforts, they do not directly pertain to the digital preservation strategy itself.
