摘要
针对大容量移动存储设备在复制大型文件过程中发生故障而无法进行断点续传的现象,提出了采用双线程循环执行模糊检查点的算法来实现适用于大容量移动存储设备的断点续传技术,并对算法的可实现性和有效性进行了简单的分析,改进了采用数组或链表实现的断点续传技术,提高了大容量移动存储设备的复制成功率.
In view of the fact that MSF, in copying large files, may break down and fail in continual transfer from disconnect position, the arithmetic of double threads circulation is proposed to execute fuzzy checkpoint, applyed to the MSF of device, conducting some analysis for the realiability and validity of the arithmetic. It will ameliorate the former technology that adopts array or chain table, improving the copy efficiency at MSF.
