CPIO is a Unix archive format used in Linux initramfs images and RPM packages. It preserves device files, sparse files, and Unix permissions while supporting streamable read/write operations.
7Z is a high-compression archive format from the 7-Zip project. It achieves significantly better compression ratios than ZIP using LZMA/LZMA2 algorithms.
