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:

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.

You can skip compression while still including files by setting the compression level to 0 (store).

Tell gzip/bzip2/7z/etc not to compress already-compressed files?

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.
