How can the data recovery tool in Kirin OS help you retrieve lost files?

Introduction:
In the daily use of computers, we often encounter accidental deletion of files, disk damage, virus infection, etc., resulting in the loss of important data. Kirin operating system provides a powerful data recovery tool that can help users retrieve lost files. This article will introduce how to use the tool and provide code examples to help readers understand how to apply it to recover lost files.

1. Overview of data recovery tools in Kirin operating system

Kylin operating system provides a data recovery tool called "extundelete". It helps users recover accidentally deleted files in the file system. "extundelete" is based on recovering accidentally deleted file attributes on the file system. It scans the unused space in the file system and recreates the index nodes and data blocks of the deleted files, thereby achieving file recovery.

2. How to use data recovery tools

1. Install the "extundelete" tool
   First, we need to install the "extundelete" tool in the Kirin operating system. Open the terminal and execute the following command to install:

sudo apt-get install extundelete

2. Perform data recovery
   After the installation is completed, we can execute the following command to perform data recovery Restore operation:

sudo extundelete /dev/[device name] --restore-all

where [device name] refers to the device from which you wish to restore files (for example, / dev/sda1). After executing the above command, "extundelete" will scan the unused space of the specified device and try to recover all deleted files.

   Once the scanning and recovery operation is completed, "extundelete" will generate a folder named "RECOVERED_FILES" in the root directory of the specified device. In this folder you will find all successfully recovered files and folders. You can use the command line or a file manager to access and copy these files.

3. Code Example

The following is a simple Python code example that demonstrates how to use the "extundelete" tool to perform data recovery operations:

import os
import subprocess

def recover_files(device_name):
    command = f"sudo extundelete {device_name} --restore-all"
    os.system(command)

device_name = "/dev/sda1"  # 替换为你的设备名称
recover_files(device_name)

The above code passes Call system commands to perform data recovery operations. You can embed it into your code according to your needs to achieve automated data recovery.
