BZ2
Bzip2 CompressedBlock-sorting compression format using the Burrows-Wheeler algorithm. Offers better compression than gzip at the cost of speed, commonly used for .tar.bz2 archives.
Best for
Source code archivesLinux distributionsBackup compressionLarge file compression
Advantages
- + Better ratio than gzip
- + Good for text
- + Widely available on Unix
- + Parallel variants (pbzip2)
Limitations
- − Slower than gzip
- − High memory usage
- − Single file only
- − Surpassed by xz
Target
7Z
7-Zip ArchiveHigh-compression archive format by Igor Pavlov using the LZMA/LZMA2 algorithm. Typically achieves 30–70% better compression ratios than ZIP. Open-source and free under LGPL.
Best for
Maximum compressionLarge file archivingSoftware distributionSpace-constrained backups
Advantages
