Abstract

The invention provides a method and device for cloning NTFS volumes between disks. The method includes: when cloning is carried out among different disks, determining the cluster size of the source volume and the cluster size of the target volume; if the cluster size of the source volume is smaller than the cluster size of the target volume, cloning the data stored in each cluster of the source volume into each cluster of the target volume; based on a file identifier corresponding to the data, adjusting the data stored in each cluster of the target volume, and reconstructing each meta-file corresponding to the target volume based on the data stored in each cluster of the target volume, so that the data is directly copied into the target volume from the cluster of the source volume, the system consumption of frequently opening and closing the files is saved, and the copying efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of disk partition management, in particular to a method and device for cloning NTFS volumes between disks. Background technique [0002] At present, the disk volume format commonly used by the operating system is NTFS (New Technology File System) file system format. When the volume adopts the NTFS format, the volume can store data in units of clusters, and one data can occupy one or more clusters. Clusters It is the smallest disk unit used in the NTFS format. The size of a cluster is an integer multiple of the size of a sector, and the size of a cluster is fixed when it is formatted. A sector is the basic unit of disk reading and writing. With the development of storage technology, the sector size of the disk gradually changes from 512k to 4k, which means that there is data copying between different disks, and the copying efficiency when copying data between different disks is currently low. Contents of th...
