About lrzip
lrzip (Long Range Zip) is a compression program designed for large files. It first looks for repeated data over long distances within a file, which ordinary compressors with small windows miss, and then compresses the result with a back end such as LZMA or ZPAQ.
It works best on big inputs like disk images, backups and source trees, and the included lrztar script handles whole directories. Newer versions note that their format is not backward compatible with older releases.
Strengths
- Finds redundancy far apart in very large files
- Includes LZMA and ZPAQ compression back ends
- lrztar wrapper for compressing directories
Limitations
- Newer format is not backward compatible with older versions
- Gains are small on small files
- Command-line only

Alternatives to lrzip
Compare allSoftware that can replace lrzip for an important use case, and what changes if you switch.
Zstandard
Meta's compression tool that hits near-zlib ratios at far higher speed, now used across Linux and modern filesystems.
Zstandard trades some ratio for much higher speed, offers a long-range mode for distant repetition, and runs on Windows, macOS and Linux with a standardised format.
XZ Utils
The standard command-line tool for creating and reading .xz files.
XZ Utils uses the widely supported .xz format with strong LZMA2 ratios on every platform, though without lrzip's long-distance redundancy search, and high levels are slow.
zpaqfranz
Keep compressed, versioned archives of changing files.
zpaqfranz is an MIT-licensed archiver that deduplicates data and keeps versioned snapshots of changing files, running on Windows, macOS and Linux.
bzip3
A command-line compressor and library intended as a stronger successor to bzip2.
bzip3 is a command-line compressor and library aimed at large text and source archives, with cat, grep and less style helpers, but a less widely supported format.
Lzip
A command-line lossless compressor using a simplified LZMA, designed for long-term archiving and data safety.
Lzip focuses on long-term archiving with integrity checks and data recovery options, using a simplified LZMA, but is single-threaded without plzip.
Kanzi
A multi-threaded lossless data compressor written in Java with selectable transforms and entropy codecs.
Kanzi is a multi-threaded Java compressor with runtime-selectable transforms and entropy codecs, requiring a Java runtime and using its own format.
