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 ?
Scripts (e.g., PERL) can be written to customize compression levels based on file extensions. 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,
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. For large file sets
