Abstract

The embodiment of the invention discloses a data recovery method and device, computer equipment and a readable storage medium. The method comprises the steps of obtaining a first sample and a second sample of each sector file to obtain a first sample queue and a second sample queue; carrying out sample matching on the first sample queue and the second sample queue according to the size informationof the two samples, and if the size information is equal, judging that the samples are matched until at least two groups of matched samples are obtained; based on the cluster numbers and the sector numbers of the two groups of matching samples, calculating the number of sectors of each cluster and the number of initial sectors of the first cluster of the storage device according to a preset relation function; obtaining a target cluster number of a target recovery file from the first sample queue, and calculating a target sector number of the target recovery file according to the relation function; and recovering the target recovery file according to the target sector number and the target cluster number. Advantages of two sample acquisition modes are combined, and a complete attribute ofa user and a file recovery result of data are provided.

Description

technical field [0001] Embodiments of the present invention relate to the field of computer technology, and in particular, to a data recovery method, device, computer equipment, and storage medium. Background technique [0002] Data recovery (Data recovery) refers to the rescue of electronic data lost on desktop hard disks, notebook hard disks, server hard disks, storage tape libraries, mobile hard disks, U disks, digital memory cards, Mp3 and other devices through technical means. and recovery techniques. [0003] ExFAT file system is currently a commonly used file system type for external devices, such as U disk, mobile disk, and SD card. This file system has the characteristics of supporting large capacity, large files, fast file location, cross-operating system support, and wide application range. Currently, commonly used recovery techniques mainly include quick recovery, formatted recovery and deep recovery. [0004] However, after research on the use scenarios of rec...
