提出一种逻辑卷有效数据的数据一致性检测方法。本地数据中心使用Windows卷影拷贝数据,保证一致性检测过程不被中断,通过分析本地数据中心发送到远程备份中心的位图信息,保证远程备份中心数据读取的准确性。实验证明,这种一致性检测方法是有效的。
A method for data consistency checking based on efficient data of logical volume is presented, the operation of local data server can continue without interrupt thanks to the use of a real-time volume shadow copy for Windows, the remote backup server analyzes the bitmap of local data server to guarantee the accurate for reading data from backup storage pool. According to the result of experiment, this method for data consistency checking is effective.
