## プロジェクトの歴史と使われ方

Tarsnapper is a command-line wrapper around Tarsnap that defines backup jobs and expires old archives according to flexible Grandfather-father-son-style retention intervals.

### プロジェクトの歴史

The public repository dates to 2010. Tarsnapper developed as a Python utility for describing multiple backup jobs in YAML and for applying retention rules to archives whether or not Tarsnapper created them. Its design avoids fixed weekly or monthly generations and instead chooses archives that best satisfy user-supplied time deltas.

### 採用の歴史

A Debian changelog records an initial package release in 2012, while the official README documents pip installation. The supplied metadata records current Homebrew and Nix packages, reflecting the tool's continued niche in Unix backup automation.

### 使われ方

Users can run a one-off backup with --target, --sources, and --deltas, or pass a YAML job file with -c. The make command creates a backup and applies retention; expire can prune existing archive sets independently, and --dry-run previews deletions. Tarsnap itself remains responsible for its configuration and keyfile.

### パッケージ好きにとっての重要性

Tarsnapper is a package-nerd utility because it converts a hosted backup CLI into reproducible cron-friendly jobs with explicit retention policy, while remaining composable with archives created by other scripts.

### タイムライン

- 2010: The public Tarsnapper repository was created and version 0.1 was tagged.
- 2012: The Debian changelog recorded an initial package release.
- 2020: Version 0.5 was tagged after continued retention-rule maintenance.
- Current package metadata: Homebrew and Nix distribute Tarsnapper.

### Related projects

- Tarsnap provides the underlying encrypted backup service and command; the README contrasts Tarsnapper's retention approach with tarsnap-generations.
