The 6 Best Linux File Recovery Software

It’s fair to say that most of us lose essential data in our computers either through accidental deletion, virus attacks, permanent removal of files, etc. at some point. Some of these files contain critical information that cannot be assumed and needs recovery. In this post, we will discuss some of the best data recovery available for Linux systems. The fantastic part is that most of them are opensource and freely available for use.

What is Data Recovery?

The process of Data recovery is the retrieving of either lost, damaged, inaccessible, or corrupted data from storage devices. They can range from storage media like Hard drives, SSD, USB drives, DVD/CD, and other electronic storage devices.

How is it possible to recover the data after deletion?

As strange it may sound, the data is not ‘actually’ deleted from the hard disk after you remove the file from your Linux system (or any OS if it matters) using the delete key. The operating system just marks the memory sector of the deleted file location as available space for the next write sequence. It means anyone can use a special tool to get access to that memory sector and recover the data before other data overwrites it. The special tool I’m talking about is the File Recovery tool.
