Part 2. How to Recover Files with Linux Data Recovery Software Tools
Tools offer the optimal solution for performing Linux data recovery on Ext2/Ext3 drives. Download the data recovery software and follow the guide below to retrieve your lost files: 1. **Download Data Recovery Software**: First, visit the official website of a reliable data recovery software such as tools, Recuva, or TestDisk. Choose the appropriate version for your Linux distribution and download it. 2. **Prepare a Live USB/DVD**: Since you need to access the affected Ext2/Ext3 drive from outside of the possibly compromised system, create a live USB or DVD with a Linux distribution like Ubuntu or Linux Mint. 3. **Boot from Live USB/DVD**: Insert the live USB or DVD into your computer and restart it. Set your BIOS/UEFI settings to boot from the USB/DVD. 4. **Mount the Drive**: Once you've booted into the live Linux environment, locate the Ext2/Ext3 drive that needs recovery. Use the 'Disks' utility (also known as 'palimpsest') or command line tools like 'fdisk' or 'lsblk' to identify the drive's mount point. 5. **Install Data Recovery Software**: Open a terminal and install the downloaded data recovery software using the package manager. For example, if you downloaded tools, use commands like: ``` sudo apt-get update sudo apt-get install gdebi sudo gdebi path/to/tools-recovery-software.deb ``` 6. **Run the Data Recovery Software**: Launch the installed software, and it should detect the mounted Ext2/Ext3 drive. Select the drive and initiate the scan. 7. **Scan the Drive**: The software will perform a deep scan to locate lost files. This process may take some time depending on the size of the drive. 8. **Preview and Recover Files**: After the scan is complete, preview the recoverable files. Select the files you want to save and choose a safe location on another drive to store them. 9. **Save the Recovered Files**: Click on 'Recover' or a similar option to start the recovery process. Wait until the software finishes saving your files. 10. **Verify Files**: Once the recovery is done, check the recovered files for completeness and functionality. Remember, prevention is always better than cure. Regularly back up your important data to avoid potential data loss situations.
Step 1. Install and launch the file recovery software on your Windows computer. Select the precise location where you lost the files and click the "Scan" button.
Step 2. The software will instantly begin scanning the drive, and the erased files will be displayed shortly. If you locate the files you need while the scan is in progress, you can stop the scan. To swiftly locate the target file, you can utilize the file format filter.
Step 3. Select the files you want to recover, such as Word documents, Excel files, PDFs, photos, videos, or emails, and then click the "Recover" button. You can choose a different location to save the recovered files.
Part 3. How to Safeguard Your Linux Data
To protect your PC from data loss issues, the ideal solution is to create a backup of your data beforehand. You can manually copy the data to another location, or you can utilize a file backup software like Todo Backup. This tool allows you to back up your system, files, and folders, and restore them effortlessly. It's a Windows application, but you can also create a WinPE bootable disk. This way, you can backup your data without booting into Windows. Simply boot from your emergency disk and follow these steps:
Step 1. When you use Todo Backup for the first time to back up files, click Create backup on the home screen, and then click the big question mark to select backup contents.
Step 2. Since you're going to back up files and folders on your computer, proceed with the "File" backup mode. Here, you can choose to back up pictures, videos, documents, and all other file types.
Step 3. Follow the paths to find the files, folders or directories you want to back up, select them all and click "OK".
Step 4. Next, you need to choose a backup location to save and store the backup.
Step 5. Todo Backup enables users to save backup files to any device that is convenient for you, such as a local hard drive, external USB drive, SD card, network drive, or NAS drive, along with the brand's cloud drive. Personally, we recommend selecting the cloud drive before a physical drive to store important backups, due to its greater accessibility, flexibility, and security.
To access the Tools Cloud, all you need is an email registration and login.
Step 6. If you're interested in an automatic and intelligent backup schedule for the next file backup task, proceed with the "Options" setting. Here, you can encrypt a confidential file backup, compress the backup image size, or customize a backup scheme to instruct the software on when to initiate the subsequent backup.
