About BZIP2 Compression

BZIP2 uses the Burrows-Wheeler algorithm to achieve better compression ratios than GZIP, though it's slower. It's commonly used for compressing large files and archives on Linux/Unix systems.

BZIP2 vs GZIP

  • Compression: BZIP2 typically achieves 10-15% better compression than GZIP
  • Speed: GZIP is faster, BZIP2 offers better compression
  • Use Cases: BZIP2 is preferred for archiving and long-term storage where compression ratio matters more than speed

Common Uses

  • Archives: .tar.bz2 archives are common on Linux systems
  • Large Files: Better compression for large data files
  • Long-term Storage: When storage space is more important than compression time
