恢复是实现容错系统容错目的和提高系统可用性的重要环节。基于自行研制的TMR容错服务器系统 ,提出了一种以检查点为基础的进程复制恢复技术 ,主要介绍恢复机制的整体结构和实现的关键技术—检测点保存与恢复技术(checkpointing/restart)
Recovery is to achieve fault-tolerant system fault-tolerant purposes and improve system availability an important part. Based on the self-developed TMR fault-tolerant server system, this paper proposes a checkpoint-based process replication recovery technology, which mainly introduces the overall structure of the recovery mechanism and the key technologies of implementation - checkpointing / restart,
