Problems solved by technology

At present, the deletion recovery technology based on the GlobalFs file system is not yet mature, and there are few related literatures, which cannot meet the urgent needs of the field of computer forensics security.
When the GlobalFs file is deleted, no software has been found at home and abroad to support the deletion and recovery of the GlobalFs file system, which makes it impossible to in-depth forensics of deleted files in the GlobalFs cluster file system

Abstract

The invention provides a GlobalFs deleted file recovery method and system, and the method comprises the steps: judging whether the value of MetaLength in a to-be-processed Direct index is equal to theactually needed length of metadata of the to-be-processed Direct index or not, and judging that the Direct index for pointing to a deleted INODE exists in the to-be-processed Direct index if not, setting a metadata range of the Direct index used for pointing to the deleted INODE, and recording the metadata range as a range M; and starting from the starting point of the range M, creating a new Direct index, searching the INODE by utilizing the new Direct index, judging whether the searched INODE is a directory or not, and if not, indexing the deleted file pointed by the INODE according to thesearched INODE. According to the method, the deleted GlobalFs files can be recovered from the storage medium without the need for GlobalFs operation or ISCSI cluster service operation.

Description

technical field [0001] The invention relates to the field of computer forensics security technology, in particular to a method and system for recovering GlobalFs deleted files. Background technique [0002] The GlobalFs file system is a cluster file system running on general-purpose hardware. It is widely used in file sharing of cloud servers. With the development and popularization of cloud services, its deleted file recovery technology will be an important part in the fields of smart device security and network information security. A hot spot of concern. At present, the deletion recovery technology based on the GlobalFs file system is not yet mature, and there are few related literatures, which cannot meet the urgent needs in the field of computer forensics security. When the GlobalFs file is deleted, no software has been found at home and abroad to support the deletion and recovery of the GlobalFs file system, making it impossible to obtain evidence for the deleted file...
