Research on disaster recovery and backup technology for long-term preservation of electronic archives
电子档案长期保存的容灾备份技术研究

摘要

本文围绕电子档案长期保存的容灾备份技术展开研究，重点探讨如何在多变的技术环境和复杂的信息生态中，实现电子档案的高可靠性与高可用性。通过分析常见的存储介质失效、硬件损坏、网络攻击及自然灾害等风险，结合多副本冗余、分布式存储、异地容灾与云备份等技术手段，提出了一套高效安全的容灾备份策略。研究表明，通过合理设计数据分级保护、跨区域异构存储及实时监测机制，可有效降低数据丢失风险，确保档案信息的完整性与可追溯性，为电子档案的长期安全保存提供可行方案。

Abstract

This study investigates disaster recovery and backup technologies for long-term preservation of electronic archives, focusing on achieving high reliability and availability in dynamic technological environments and complex information ecosystems. By analyzing risks such as storage medium failures, hardware damage, cyber attacks, and natural disasters, the paper proposes an efficient and secure disaster recovery strategy incorporating multi-replica redundancy, distributed storage, off-site disaster recovery, and cloud backup technologies. Research findings demonstrate that through rational design of data tiered protection, cross-regional heterogeneous storage, and real-time monitoring mechanisms, data loss risks can be effectively mitigated while ensuring archival information integrity and traceability. This provides a practical solution for long-term secure preservation of electronic archives.
