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 ## ソースデータベース詳細 - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** ddrescue - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## 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 - 1.30-3.fc44: normalized package name match | Fedora Rawhide package metadata: ddrescue from https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Everything/x86_64/os/repodata/e5ca8ce900cd68f5419e1c39ae517343100b306336cbaeb70a3c153121d95094-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 - 1.99.22-1.3: normalized package name match | openSUSE Tumbleweed package metadata: dd_rescue from https://download.opensuse.org/tumbleweed/repo/oss/repodata/be8d3611d25469107f32075a1697e69ec57a2b850b42348a658cc671ad5ec2b50760d02c3e59524d50da9a11d5be799bdaffba2e166e8ca8858512e3c0bd665d-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 ## 関連リンク - [Terminal utility packages](https://www.automicvault.com/ja/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://www.automicvault.com/ja/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Database and data packages](https://www.automicvault.com/ja/pkg/database-data-tools/) - Matched database, SQL, migration, or data-store metadata. - [Web development packages](https://www.automicvault.com/ja/pkg/web-dev-tools/) - Matched web development metadata. - [lziprecover](https://www.automicvault.com/ja/pkg/brew/lziprecover/) - Shares av.db curated category or tags: cli, data-recovery, system. - [par2](https://www.automicvault.com/ja/pkg/brew/par2/) - Shares av.db curated category or tags: cli, data-recovery, system. - [recoverpy](https://www.automicvault.com/ja/pkg/brew/recoverpy/) - Shares av.db curated category or tags: cli, data-recovery, system. - [testdisk](https://www.automicvault.com/ja/pkg/brew/testdisk/) - Shares av.db curated category or tags: cli, data-recovery, disk-recovery, system. - [bash](https://www.automicvault.com/ja/pkg/brew/bash/) - Shares av.db curated category or tags: cli, gnu, system. - [bc](https://www.automicvault.com/ja/pkg/brew/bc/) - Shares av.db curated category or tags: cli, gnu, system. - [coreutils](https://www.automicvault.com/ja/pkg/brew/coreutils/) - Shares av.db curated category or tags: cli, gnu, system. - [cpio](https://www.automicvault.com/ja/pkg/brew/cpio/) - Shares av.db curated category or tags: cli, gnu, system. - [gzip](https://www.automicvault.com/ja/pkg/brew/gzip/) - Local package facts share a topical domain.
