Analysis of Methods for Creating Media for Long-Term Data Storage

Long-term storage of electronic documents is essential for successful development in various fields of economy, science, and culture. While producing enormous amounts of data, modern society faces challenges related to creating systems for long-term data storage, as well as methods for securing these storages against unauthorised access. As the body of knowledge available to humanity continues to expand, and so do data recording technologies, the importance of developing long-term storage methods increases. We need to ensure long-term storage of genetic and medical and biological information, storing data from routine environmental monitoring, including data from hydro-meteorological monitoring for long periods, seismic tomography data, government records, scientific heritage data, namely published results of scientific research and experiments, bibliographic and factual databases, information about scientists, their scientific activities, publications, projects, etc., information related to complex engineered facilities, and information on cultural heritage of humanity. Several types of data require continuous storage for decades, like archival storage, and even for hundreds or thousands of years, when dealing with genetic data or data that can impact the survival of future generations [3]. Special media for data storage are an important element of systems for long-term storage of electronic documents. Therefore, development of such media represents a scientific and technological problem of high importance. Its urgency is due to the fact that no existing technical means can ensure long-term data storage.
