Regularly backing up data on a Network Attached Storage (NAS) system is essential to prevent data loss. A common scenario is to use a NAS as a centralized storage device for photos and videos taken by smartphones. In this setup, it is crucial to periodically burn the files onto DVDs to ensure their safekeeping. Theoretically, if the DVDs remain in good condition, the data stored on them will not be lost, providing a reliable means of archiving valuable digital content.
