TAR vs XZ
Een uitgebreide vergelijking van TAR Archive en XZ Compressed — bestandsgrootte, kwaliteit, compatibiliteit en welk formaat het beste past bij jouw workflow.
TAR Archive
Archives & CompressedTAR is a Unix archive format that bundles files together without compression. It is commonly combined with gzip or bzip2 for compressed archives and is the standard for Linux software distribution.
Over TAR-bestandenXZ Compressed
Archives & CompressedXZ provides very high compression ratio using LZMA2, common in Linux packages.
Over XZ-bestandenVergelijking van sterke punten
TAR Sterke punten
- Streamable — you can tar files straight to a network pipe, no seek needed.
- Preserves Unix permissions, ownership, symbolic links, and timestamps.
- Universally supported on Unix-like systems.
- Simple format — the GNU tar source has been stable for decades.
- No compression overhead — pair with gzip/xz/zstd as needed.
XZ Sterke punten
- Best-in-class compression ratio among mainstream tools.
- Streaming-capable — can pipe through network.
- Multi-threaded compression available.
- Mature on every Linux distribution.
- Supports integrity checking (CRC32, CRC64, SHA-256).
Beperkingen
TAR Beperkingen
- No built-in compression — plain .tar files are the same size as their contents.
- No random access — reading one file requires scanning from the start.
- Windows tooling is second-class — PowerShell only added native tar in 2018.
- Multiple incompatible header variants (v7, ustar, POSIX, GNU) over the years.
XZ Beperkingen
- Slow compression at high levels — 3-5× slower than gzip.
- Memory-hungry: xz -9 can need 700+ MB to compress.
- 2024 supply-chain backdoor damaged trust in the project.
- Zstandard outperforms xz at similar ratios with less memory.
