历史

项目历史与用法

Tarsnap is a secure, efficient command-line online backup service for Unix-like systems, centered on client-side keys, deduplication, and pay-for-actual-usage storage. 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.

项目历史

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.

采用历史

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.

使用方式

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.

为什么软件包爱好者会关心

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.
