Three open-source utilities dominate the Linux data recovery landscape: <strong>GNU ddrescue</strong> for block-level disk imaging, <strong>TestDisk</strong> for partition recovery, and <strong>PhotoRec</strong> for file carving. Each serves a distinct purpose in the recovery toolkit, and understanding when to deploy which tool is essential for any self-hosted infrastructure operator.</p>
