基于事件的连续数据保护系统研究

针对现有连续数据保护系统存在恢复点选择困难、数据一致性差和无法支持事务级数据恢复粒度的问题，提出了基于事件驱动的连续数据保护恢复系统（EBRS）解决方案，给出了EBRS的三个核心组件应用感知模型、应用协同模型和事件恢复视图的设计与实现方案。在Oracle环境下实现了EBRS的关键功能，实验结果表明，基于事件驱动的连续数据保护恢复系统具有恢复粒度细、恢复效率高、数据一致性好的特点，具有广阔的应用前景。...

Traditional continuous data protection （CDP） had difficult in selecting the fight one from many restore points, could not guarantee consistence of data recovery and could not support transaction-level recovery for the application. This paper suggested an event-based continuous data protection recovery system, and gave the detail design of the three core components including the application-aware model, the application-collaborative model and the event-based recovery view. It implemented the key functions of EBRS in Oracle database environment. Experiment results show that event-based continuous data protection recovery system has the features of supporting fine-grained data recovery, efficient recovery and good data consistence,
