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.
