BZ2 at a glance
BZ2
Convert to BZ2 when you need compatibility with workflows that already expect bzip2, especially for source distributions, archival mirrors, or legacy Unix automation.
It is suitable for text-heavy datasets, exported reports, and tar.bz2 packages where somewhat better compression than gzip is useful and decompression speed is not the top priority.
Choose it when legacy compatibility matters; for new large-scale archival or transfer workflows, xz or zstd are often more attractive.
TAR.ZST at a glance
TAR.ZST
Convert to tar.zst when you want a filesystem-preserving archive with modern compression performance.
It is ideal for backups, package artifacts, large project exports, and internal or public technical distributions where both throughput and compactness matter.
It is often the best modern default when you control the receiving environment and can assume zstd-capable tooling.
