How To Install ddrescue on CentOS 8
Introduction
In this tutorial we learn how to install ddrescue on CentOS 8.
What is ddrescue
GNU ddrescue is a data recovery tool. It copies data from one file or block device (hard disc, cd-rom, etc) to another, trying hard to rescue data in case of read errors. GNU ddrescue does not truncate the output file if not asked to. So, every time you run it on the same output file, it tries to fill in the gaps.
