【摘要】 档案数字资源是国家信息资源的重要组成部分，其长期安全保存与存储载体息息相关。目前，信息长期存储载体正从磁带、硬盘、光盘、胶片向玻璃盘方向发展。本文首先列举了常见档案数字资源存储载体类型，接着重点介绍了玻璃存储技术及其在档案数字资源长期保存中的潜在应用，然后对各类档案数字资源存储载体的特性进行比较分析，最后提出了“4-3-2-1”备份策略，通过建立包含在线存储、离线备份、异地备份、异质备份在内的完整的存储备份策略，以满足档案数字资源长期安全保存的要求。更多还原

【Abstract】 Digital archival resources are an important component of national information resources, and their long-term safe preservation is closely related to storage media. Currently,the long-term storage media for information is evolving from tapes, hard drives, optical discs, and film towards glass media.This article first enumerates the common types of storage media for digital archival resources. Then it focuses on introducing glass storage technology and its potential application in the long-term preservation of digital archival resources. After that,it compares and analyzes the characteristics of various storage media for digital archival resources. Finally, it proposes a "4-3-2-1" backup strategy that meets the requirements for long-term safe preservation of digital archival resources by establishing a complete storage and backup strategy that includes online storage, offline backup, remote backup, and heterogeneous backup.更多还原
