For large file sets, 7z provides multi-core compression, making it faster than many single-threaded alternatives. More details on using 7z with block devices ?
Tell gzip/bzip2/7z/etc not to compress already-compressed files? K42.7z
The 7z command is a powerful archiving tool that supports multi-threaded compression (LZMA2) and split archiving. Here is a write-up summarizing key technical considerations when using 7z: For large file sets, 7z provides multi-core compression,
Scripts (e.g., PERL) can be written to customize compression levels based on file extensions. The 7z command is a powerful archiving tool
You can skip compression while still including files by setting the compression level to 0 (store).
Using algorithms like LZ4 is recommended for data that is already compressed, as it prevents inefficient re-compression and speeds up the process, achieving high compression/decompression speeds.
7z allows for non-solid mode, which is beneficial when specific files within a large archive need to be accessed quickly, as it reduces the need to decompress the entire archive.
