Linux Restore mistakenly delete files

Environment requirements: Create a new file system in the virtual machine, creating several files in the file system, the simulation files are mistakenly deleted in the recovery experiment.

Compiling and installing the Extundelete package

First Use Yum Warehouse Installation Dependency Packages E2fsprogs-libs , E2fsprogs-devel ( Yum Warehouse production is described in the previous article, here no longer the fat complaint)

Mount Windows System shared folder, view package (mount operation see GO)

Tar Unzip Extundelete Source Code Package

before the first compilation of the installation, you have to confirm the compilation environment, with Yum Warehouse Installation Environment Package GCC , gcc-c++, make

then Enter Extundelete the folder after the package is unzipped, the configuration is compiled and installed

Simulate accidental deletion and perform recovery operations

Add a new hard disk to the virtual machine and restart the virtual machine for it to take effect, then create the partition and mount the specified mount point after formatting

Enter the mount point and create several files inside

Simulate a mistake delete operation

Immediately after the accidental deletion, exit the mount point and unmount the file system.

Then enter the Extundelete/dev/dd1–inode 2 command to view the file status in the file system.

Enter the Extundelete/dev/sdd1–-restore-all command to restore everything under the file system

The recovered files will be in a recovered_files subdirectory that appears in the current directory.

Experiment completed
