Abstract
The invention discloses a file recovery method and device of a linux system. The file recovery method and device of the linux system are used for recovering Ext4 files which are deleted through rm by mistake on a linux server, and avoiding enormous losses caused due to the fact that important data of the server are lost. The method includes the steps that after file data of an Ext4 file system are deleted by mistake, a disk partition where the file data which are deleted by mistake are located is recorded as a disk partition to be recovered; a root directory of the linux system is switched to; the position of the disk partition to be recovered is sought for in a directory tree to obtain position information; the disk partition to be recovered is unloaded according to the position information; an inode value is check to confirm that the file data which are deleted by mistake are located in the root directory of the linux system at present; a disk traversal tool is downloaded and installed; the disk partition to be recovered is traversed, a list of all files with invalid inode information is obtained, and the file data which are deleted by mistake are found out; the inode information corresponding to the file data which are deleted by mistake is changed to be valid.
Description
Technical field
The present invention relates to field of computer technology, relate to especially a kind of file restoration methods and device of linux system.
Background technology
Linux is class Unix (You Nisi) operating system of a set of free use and Free propagation, is the operating system of a multi-user, multitask, support multithreading and many CPU.It supports 32 and 64 hardware.Linux has inherited Unix take the design philosophy that network is core, is the multiple-user network operating system of a stable performance.
The basic thought of Linux has 2 points: the first, and all are all files; The second, each software has definite purposes.Wherein article one is exactly that all in system are all summed up as a file in detail, comprises that order, hardware and software equipment, operating system, process etc. are for operating system nucleus, is all regarded as having the file of characteristic separately or type.
Linux file system has 4 three kinds of Ext 2, Ext 3, Ext.Wherein, Ext4 (The fourth extended file system, the 4th extended file system) being a kind of expansion Journal File System for Ext 3 systems, is to be the 4th edition of the original extended file system (ext or extfs) of Linux exploitation specially.
In Linux file system, file carries out unique identification by inode (a kind of data structure comprises documentary all information).Each file has inode and block (piece) to form, and inode is the elementary cell that file system forms, the base attribute of its in store file (size, authority, owner organize etc.) and the positional information of depositing.And block is used for storing data.Similar key-value (clue-value) storage system, inode is exactly key, and the corresponding value of block, searches by key the value that key is corresponding.The dictionary of similar python (high-level programming language of a kind of explanation type, object-oriented, dynamic data type).，
The software of deleting by graphic interface on Linux server generally can recover in recycle bin, and the data of using " rm-rf* " order to delete by order line are difficult to recover.The disk of Ext2 file layout can recover by " debugfs instrument " conventionally, the data in magnetic disk of Ext3 file layout can recover by " ext3rescue instrument ", but because the disk structure of Ext4 form, can not be directly with previous recovery instrument, the recovery that recovers at present Ext4 form data in magnetic disk is very difficult.
