LZ4 at a glance
LZ4
Convert to LZ4 when fast compression and fast restore matter most.
It is a good target for transient archives, backups that must be restored quickly, CI artifacts, log shipping, and large data movement inside infrastructure you control.
Use it when wall-clock speed is more important than the smallest final file.
For internet distribution or long-term cold storage, xz or zstd may make more sense; LZ4 shines in performance-sensitive internal pipelines.
TAR.XZ at a glance
TAR.XZ
Convert to tar.xz when you need a compact Unix-friendly archive for source releases, firmware packages, research data, or server-side bundles where the recipients are expected to use technical tooling.
It is the right target when smaller archive size is worth slower compression.
Choose it over tar.gz for distribution efficiency, and over plain xz when you need to preserve a full directory tree.
