Introduction

Deletion of files and data can be a frustrating experience, especially when it comes to important work or personal files. In Linux, deleting files can be done using various methods, but restoring them can be a challenge. In this article, we will explore the different methods to restore deleted files in Linux, including the use of command-line tools, file systems, and third-party software.

Method 1: Using Command-Line Tools

1. Using find to locate deleted files

• find is a powerful command-line tool that allows you to search for files based on various criteria, including their location, size, and modification date.
• To use find, you need to specify the file system you want to search on, such as / (root directory) or /home/user/ (user directory).
• You can use the -name option to search for files with a specific name, and the -size option to search for files with a specific size.
• For example:

  • find / -name "*.txt" -size 1024M -exec rm {} ;

2. Using rsync to synchronize deleted files

• rsync is a command-line tool that allows you to synchronize files between two locations.
• To use rsync, you need to specify the source and destination file systems, as well as the files you want to synchronize.
• You can use the -r option to recursively synchronize files, and the -f option to force the synchronization process.
• For example:

  • rsync -r /home/user/ /home/user/backup/

3. Using tar to extract deleted files

• tar is a command-line tool that allows you to extract files from a tar archive.
• To use tar, you need to specify the tar archive file, as well as the files you want to extract.
• You can use the -x option to extract files, and the -f option to force the extraction process.
• For example:

  • tar -xvf /home/user/deleted_files.tar

Method 2: Using File Systems

1. Using the ext4 file system

• The ext4 file system is a widely used file system that supports file deletion and recovery.
• To use the ext4 file system, you need to mount the file system on your Linux system.
• You can use the mount command to mount the file system, and the umount command to unmount the file system.
• To delete a file on the ext4 file system, you can use the rm command, and to recover a deleted file, you can use the fsck command.

2. Using the btrfs file system

• The btrfs file system is a file system that supports file deletion and recovery.
• To use the btrfs file system, you need to install the btrfs package on your Linux system.
• You can use the btrfs command to delete a file, and to recover a deleted file, you can use the btrfs command with the fsck option.
