摘要: 基层广播发射台站数据安全运维的核心痛点在于“有限资源与差异化数据保护需求不匹配”,分类分级备份机制是解决该矛盾的关键技术路径。针对发射台站“数据聚焦设备运行与指令交互”的核心属性,构建“数据安全等级备份技术参数”映射模型,通过备份频率系数、冗余度及 RTO 达标率优化三类公式计算,并结合基层台站实测数据,验证公式可行性。研究表明,通过量化参数管控,可使一级数据备份成功率、RTO达标率提升至理想的数值,为基层发射台站提供可落地的分类分级备份技术方案。

Abstract: The core pain point in data security operation and maintenance of grassroots radio transmission stations lies in the "mismatch between limited resources and differentiated data protection needs", and the classified and hierarchical backup mechanism is the key technical path to resolve this contradiction. Focusing on the core attribute of transmission stations—data focusing on equipment operation and command interaction, this paper constructs a mapping model of "data security level backup technical parameters". It verifies the feasibility of the formulas through calculations using three types of formulas (backup frequency coefficient, redundancy, and RTO compliance rate optimization) and combining with the measured data from grassroots stations. The research results show that through quantitative parameter management and control, the backup success rate and RTO compliance rate of level1 data can be improved to ideal values, providing a practical classified and hierarchical backup technical solution for grassroots transmission stations.
Key words : data security operation and maintenance; classificationbased hierarchical backup; backup frequency coefficient; RTO compliance rate

引言

根据《广播电视安全播出管理规定》(广电总局令第 62 号),基层广播发射台站需对 “发射机运行参数、信号监测数据、播出指令日志” 三类核心数据实施差异化保护[1]。当前 85% 的基层台站仍采用 “统一周期备份” 模式(如每日全量备份),这种模式存在显著弊端。对于一级数据(如实时功率参数),其对时效性要求极高,统一备份导致备份延迟超10 min,无法满足实时保护需求;而二级数据(如小时级场强记录)因统一备份,存储冗余率达 40%,造成“核心数据保护不足、非核心数据资源浪费”的双重问题[2]。在进行数据安全的调研中发现,未实施分类分级备份的台站,数据丢失事故发生率是实施台站的数倍。深入分析事故原因,其中70%的事故源于 “一级数据备份频率不足”或“三级数据过度占用存储资源导致备份失败”。由此可见,构建量化的分类分级备份机制,成为提升基层台站数据安全运维效率的关键所在,也是解决当前基层台站数据安全运维困境的必然选择[3]。
