Today we’ll be going over the best Linux data recovery tools to help you recover any data that you might have lost. If you recently deleted the files, the possibility of recovering those files increases a lot.

But don’t lose hope if you’ve deleted the files long ago. There’s still a possibility that the file data is still present on your hard drive. So read on, you might as well be able to recover all the files that you’ve lost before!

How to Choose the Best Linux Data Recovery Tools?

There are very few things that you need to consider because most of the data recovery tools work in a similar manner by accessing the fragmented bits on your hard drive.

The major differences are usually in the ease of use, user interface, and features. So let’s go over the features and functionality of the top 20 best Linux data recovery tools in this article.

1. TestDisk - Partition and Disk Recovery Tool

This is one of my favorite utilities. It’s a command-line based tool but is really easy to use and very interactive. The utility runs and starts working its magic by simply running the command.

We wrote a recent tutorial on the testdisk utility which walks you through the installation and the steps to recover files.

Some of the features of TestDisk:

  • Recover deleted partitions
  • Re-build partition table.
  • Partition backup for EFI GPT partitions
  • Rewrite MBR

2. Mondo Rescue - Network Drive Recovery Utility


Another really good command-line utility is Mondo Rescue which has a few unique features which are really helpful for people working on multiple different types of file systems. This is the one utility that has been used for decades to backup/restore/recover data from all types of storage devices tape drives too!

The SafeCopy is one of the best Linux data recovery tools and works when all else fails. This tool is used for recovering data from damaged and bad sectors on a hard drive.

SafeCopy also tries to get as much data as possible from the source drive, even resorting to some device-specific low-level operations wherever applicable.

Some of the features of SafeCopy:

  • Performs low-level IO operations to extract maximum possible data
  • Remembers arbitrary recovery position even if the source device frequently disconnects (like USB drives that can lose connection due to faulty storage)
  • Can fix errors in data on CDs, DVDs, and even Floppy drives

14. grep Command - Simple Text Data Recovery

The grep utility that we use for finding text on the terminal output is powerful enough to also help us find lost text data. Have a look at the code sample below:

grep -a -A 400 -B 25 'string to find here' /dev/sdb1 > recover.txt
  • The -a specifies grep to consider the source as a text file
  • The -A and -B specifies grep to find 25 lines before and 400 lines after this specific line is found. This allows us to get the entire text file and also, it’s better to have more data which we can later delete, than getting lesser one and having to run the command again.
  • /dev/sdb1 is the source where we want the text to be searched for. We want the text to be searched on the entire drive
  • > recover.txt will be where the output will be saved.

15. ext3grep - An ext3 File Recovery Tool

This is a command-line tool that is created for ext3 file systems for data recovery. With just two commands, you can recover and restore any deleted file that was recovered with this tool.

ext3grep --dump-name <drive>
ext3grep --restore-all <drive>

#Restored data is stored in this folder

16. ext4magic - One of the Best Linux Data Recovery Tools for ext4


This is a command-line tool like many others in the list and is available from the package repositories for most Linux distributions.

Some of the features of ext4magic:

  • Can recover entire filesystems that were recursively deleted
  • Recover accidentally overwritten files
  • Recover first-sectors of a hard disk that were accidentally overwritten

17. extundelete - An ext3grep Successor


This utility has its roots in the code of ext3grep. The ext3grep utility used the disk journal to recover files and so does the extundelete. This utility searches the disk journal for old copies of an existing inode to find more details and collectively forms it into a file.

Some of the features of extundelete:

  • Recover from ext3 and ex4 partitions (a combination of #15 and #16)
  • One of the programs to recover the file content and the file names on ext4 partitions
  • ext4magic is based on extundelete for a lot of its ext4 recovery code

18. R-Undelete - IntelligentScan Data Recovery Technology

  • MBR and GPT recovery
  • Boot sector recovery on major file systems
  • Recover files on ext, FAT, NTFS systems

19. ext3undel - A Custom Script to Simplify File Recovery

This is a script written to simplify the use of some of the complicated tools like Sleuthkit and PhotoRec and simplify them. Using these tools in combination also makes this script a more efficient method to extract more of the deleted inodes correctly.

Since this is a script that combines the functionality of multiple tools, the functionality is similar to the tools themselves.

20. The Sleuth Kit - Forensic Evidence

SleuthKit Autopsy
Sleuth Kit Autopsy

This is a tool that’s made specifically for forensic investigators to perform analysis on hard drives and collect evidence. So the Sleuth Kit uses very efficient and advanced algorithms to extract as much deleted data as possible from hard drives.

The previous tool that we talked about “ext3undel” leverages technology from the Sleuth Kit but if you would like to use this tool as a standalone one, you can use it along with it’s GUI front-end “Autopsy

Some of the features of The Sleuth Kit:

  • Timeline Analysis: View system events on a GUI
  • Keyword Search: Find keywords in text files across the entire drive (including deleted files)
  • Web Artifacts: Extract web activity data
  • Registry Analysis: Find recently connected devices using the registry data
  • LNK File Analysis: Identity recently accessed documents
  • Email Analysis: Parses email messages in the mbox format for reading and analysis
  • and many more features…


We hope you found the right tool for your data recovery needs with this article. For a basic user, pretty much any tool from the list will work. But for people who’ve special needs with file recovery, they need to find the one that has the features that they need.

Always remember though, these tools try to recover files that have been deleted based on the metadata that still remains. But that’s not a guarantee of recovery so it’s always best to have backups of all the data that’s being stored.
