It is famous among command-line and security-minded users because its normal interface is a tar-like CLI rather than a consumer backup app. ### プロジェクトの歴史 The official site describes Tarsnap as a command-line backup service for Linux, the BSDs, macOS, and other Unix-like systems. The official client repository is for developers who want to watch changes, investigate bugs, or test unreleased features, while the website recommends official release downloads for normal use. ### 採用の歴史 Official news shows active public releases and service milestones from at least 2009, including the move from beta-era web pages to the main website in September 2009, Tarsnap 1.0.26 in December 2009, bug bounties in 2011, a Tarsnap book in 2015, and Tarsnap 1.0.41 in March 2025. The supplied package-manager metadata shows Tarsnap packaged in Homebrew, MacPorts, Nix, and Arch. ### 使われ方 Users create, list, extract, delete, verify, and recover encrypted remote archives with the tarsnap CLI and related key utilities. The official man page documents keyfile and cachedir driven operation, default configuration files, archive listing, fsck/recovery modes, and examples for cron-based full-system backups. ### パッケージ好きにとっての重要性 Package nerds care because Tarsnap is a compact, scriptable backup primitive with serious cryptographic and operational opinions. Its package surface includes multiple binaries, configuration files, key generation, cache directories, man pages, and a GUI-facing initialization mode, all of which make it a classic Unix packaging case rather than a single executable. ### タイムライン - 2009-09: Official news says the non-minimalist tarsnap.com website replaced scattered beta-era information. - 2009-12: Tarsnap 1.0.26 released. - 2011-04: Official bug bounty program announced. - 2015-03: Official news notes publication of Tarsnap Mastery. - 2015-05: Official GitHub repository created for client-code development visibility. - 2022-02: Tarsnap 1.0.40 released. - 2025-03: Tarsnap 1.0.41 released with XDG config support and other changes. ### Related projects - Tarsnap GUI, tarsnap-keygen, tarsnap-keymgmt, tarsnap-keyregen, tarsnap-recrypt, tar, libarchive, scrypt, spiped. ### ソース - - - - - - input source_facts.package-manager: brew, MacPorts, Nix, Arch packaging. ## セキュリティノート broad file, network, media, or database tool signal. - **Geiger リスク:** blue / 中 - broad file, network, media, or database tool signal ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
