历史

项目历史与用法

GNU ddrescue is a data-recovery command-line tool for copying data from failing disks, optical media, or files while tracking progress in a mapfile. Its package identity is built around one job: rescue readable blocks first, keep a resumable record, and return for the difficult areas later.

项目历史

GNU ddrescue was written by Antonio Diaz Diaz and became part of the GNU software collection. The official manual describes its automatic rescue operation, non-truncating output behavior, and mapfile-driven resume strategy, all of which distinguish it from simpler dd-style copying.

采用历史

The tool became a standard package in recovery-oriented Unix toolkits because it is scriptable, resumable, and cautious around damaged input. Official GNU release announcements continued through the 1.x line, including the 1.30 release announcement in January 2026.

使用方式

Typical usage images a damaged device to a safer target while writing a mapfile, then reruns the command to retry missing or bad areas. The companion ddrescuelog tool works with mapfiles for inspecting, converting, and managing rescue state.

为什么软件包爱好者会关心

ddrescue matters to package nerds because it is the recovery tool people hope they installed before hardware starts failing. It also sits in a confusing namespace with similarly named tools, so the GNU package name, executable names, manual, and Savannah source location are important for correct curation.

时间线

2004: GNU ddrescue's early public release era begins.
2007: GNU ddrescue is already established enough for public interviews and release announcements around the 1.x line.
2024: GNU ddrescue 1.28 appears in downstream package-update announcements.
2026: GNU ddrescue 1.30 announced on the GNU info list.

Related projects

ddrescuelog is distributed with GNU ddrescue for mapfile inspection and manipulation.
dd_rescue and dd-rhelp are historically related names often contrasted with GNU ddrescue.
GNU coreutils dd is the simpler block-copying tool whose limitations often motivate use of ddrescue.
