For years, magnetic media based solutions, such as tape and hard disk drive （HDD） based archive systems, monopolize the data archiving market due to their high capacity and low cost. However, in the era of big data, rapidly increasing volume, velocity, and variety of data set bring numerous challenges to the archive systems in various aspects, such as capacity, cost, performance, reliability, power consumption, and so on. In recent years, high capacity optical media, such as bluray discs （BDs） and holographic discs, emerge with the revival of optical storage. Due to the natural simple construction of the optical media, the archive systems based on those optical media, e.g., BD library, demonstrate attractive properties, such as cost per bit, reliability, power consumption, and so on, thus become feasible options in long-term digital preservation. In this paper, we reviewed and compared both the magnetic and optical media based solutions for long-term digital preservation, followed by a summarization on techniques to improve the optical media based archive system.展开更多
数字档案资源的长期保存不仅有利于数字档案资源的可持续利用,还为档案事业高质量发展奠定资源基础。本文基于中国知网(CNKI)和Web of Science数据库,利用Co-Occurrence等可视化工具,对截至2023年12月的2 194篇国内外数字保存领域文献...数字档案资源的长期保存不仅有利于数字档案资源的可持续利用,还为档案事业高质量发展奠定资源基础。本文基于中国知网(CNKI)和Web of Science数据库,利用Co-Occurrence等可视化工具,对截至2023年12月的2 194篇国内外数字保存领域文献进行可视化知识图谱分析,系统展现该研究领域的发展脉络。结果表明:该领域研究经历了缓慢起步,快速发展阶段;国内已经形成在该领域深耕的研究机构和核心作者,且形成了一定规模的合作网络,而国外合作网络整体较为松散,存在规模较小的研究子群;研究议题方面,国内的研究侧重于数字保存的管理方式和风险规避等,而国外则侧重数字保存技术的研究;OAIS、LOCKSS等图书馆数字资源长期保存新方式和新机制的研究是国内外共同的研究热点。展开更多
