Project history and usage

Tarlz is a command-line archiver that combines tar-style archiving with lzip compression while preserving alignment between tar members and lzip members. Its niche is careful, recoverable, parallel-friendly tar.lz archives.

Project history

The official NonGNU page describes Tarlz as a massively parallel combined implementation of the tar archiver and the lzip compressor using lzlib. The official manual is copyrighted 2013-2026 by Antonio Diaz Diaz, and the official download index shows public tarlz tarball releases from 0.3 in March 2018 through 0.29 in January 2026.

Adoption history

The supplied package-manager metadata shows Tarlz available in Homebrew, Debian, Nix, and Ubuntu. That is the expected adoption path for a small Unix archiving tool: source releases from the upstream lzip project, then distribution packaging for users who need lzip-compatible backup/archive workflows.

How it is used

Tarlz is used to create and extract multimember tar.lz archives, including appendable and recoverable archive layouts. Official docs emphasize parallel decompression, appending and deleting members, safer recovery from corruption, and POSIX-style backup behavior.

Why package nerds care

Package nerds care because Tarlz argues for archive format details that ordinary tar pipelines hide: member alignment, CRC-protected metadata, corruption recovery, and parallel decoding. It is the sort of tool that matters to distribution maintainers, backup users, and compression people who care about long-term archive integrity.
