Its package identity is built around one job: rescue readable blocks first, keep a resumable record, and return for the difficult areas later. ### プロジェクトの歴史 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. ### 採用の歴史 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. ### 使われ方 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. ### パッケージ好きにとっての重要性 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. ### タイムライン - 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. ### ソース - - - - ## セキュリティノート narrow executable package without higher-risk signals. - **Geiger リスク:** グリーン / 低 - narrow executable package without higher-risk signals ## 他のパッケージマネージャ記録 - Nix - ddrescue: normalized package name match | nixpkgs package indexes: pkgs/by-name/dd/ddrescue/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - apk - ddrescue - 1.30-r0: normalized package name match | Alpine Linux edge package indexes: ddrescue from https://dl-cdn.alpinelinux.org/alpine/edge/community/x86_64/APKINDEX.tar.gz | Data recovery tool for block devices with errors | https://www.gnu.org/s/ddrescue/ddrescue.html - apk - ddrescue-doc - 1.30-r0: normalized package name match | Alpine Linux edge package indexes: ddrescue-doc from https://dl-cdn.alpinelinux.org/alpine/edge/community/x86_64/APKINDEX.tar.gz | Data recovery tool for block devices with errors (documentation) | https://www.gnu.org/s/ddrescue/ddrescue.html - dnf - ddrescue - 1.30-4.fc45: normalized package name match | Fedora Rawhide package metadata: ddrescue from https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Everything/x86_64/os/repodata/07190dc5ae9f35ae73866675fed6d95fe6e8d9fe22c9d7cdf85862cb2ed24a4c-primary.xml.zst | Data recovery tool trying hard to rescue data in case of read errors | http://www.gnu.org/software/ddrescue/ddrescue.html - pacman - ddrescue - 1.30-2: normalized package name match | Arch Linux sync databases: ddrescue from https://geo.mirror.pkgbuild.com/extra/os/x86_64/extra.db.tar.gz | GNU data recovery tool | https://www.gnu.org/software/ddrescue/ddrescue.html - zypper - dd_rescue - 1.99.22-1.5: normalized package name match | openSUSE Tumbleweed package metadata: dd_rescue from https://download.opensuse.org/tumbleweed/repo/oss/repodata/50b07339cb64c8ed4091bdbabddadc1ff5737b090e478818a195b40d8a3292861a879139b4a3987c31109699fde9fbf4a716367ddf4eef77da75f96e3193d6ed-primary.xml.zst | Data copying in the presence of I/O Errors | http://www.garloff.de/kurt/linux/ddrescue/ - MacPorts - ddrescue: normalized package name match | MacPorts ports tree: sysutils/ddrescue/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 ## Combined YAML source View the package source record on GitHub.
