The Essence of extundelete

'extundelete' is a command-line tool designed for ext3 and ext4 file systems, the default file systems for many Linux distributions. Its primary purpose is to recover files that have been accidentally deleted or lost due to filesystem corruption. By leveraging the features of these ext filesystems, 'extundelete' can perform file recovery with remarkable precision.

Installing extundelete

To harness the power of 'extundelete,' you'll first need to install it on your Linux system. On Debian-based distributions, such as Ubuntu, you can use the 'apt' package manager for a seamless installation.

The Art of File Recovery:

Now that 'extundelete' is at your disposal, let's explore some practical use cases.

1. Recovering Deleted Files: The basic syntax for recovering a deleted file involves specifying the partition and the path to the directory where the recovered file should be saved.

   sudo extundelete /dev/sdX --restore-file /path/to/deleted/file
   

2. Undeleting an Entire Directory If an entire directory was inadvertently deleted, 'extundelete' can recover it by specifying the directory path.

   sudo extundelete /dev/sdX --restore-directory /path/to/deleted/directory
   

3. Filtering Recovery Results You can filter the recovery results based on file types, making it easier to locate specific files.

   sudo extundelete /dev/sdX --restore-all --after YYYY-MM-DD
   

4. Previewing Recovery Results Before committing to the recovery process, you can preview the files that 'extundelete' intends to recover.

   sudo extundelete /dev/sdX --restore-all --dry-run
