摘要
针对目前持续数据保护(CDP)系统在远程恢复的过程中,不支持对于数据卷的读写操作,从而导致业务中断时间较长的问题,提出一种改进的备份数据远程恢复方法,通过后台恢复以及读时重定向机制,将业务流程与恢复流程重叠,支持恢复过程中上层业务对数据卷的读写操作。通过实验验证所提出的恢复方法能在恢复任务开始之后很短的时间支持数据卷的读写操作,极大地降低上层业务系统的中断时间。
During the remote data recovery process,current Continuous Data Protection system does not support to read and write data volume,causing business interruption for a long time. Against to this problem, presents an improved recovery method for remote backup data,based on background recovery and reading redirection mechanism, overlapping business process and recovery process. The experiment proves that this recovery method can significantly reduce the business system interrupt time.
