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. K42.7z

7z can be used to archive the contents of block devices, such as /dev/sda1 , by piping data from cat or similar commands. Typical Scenarios

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. Based on your request, "write-up: K42

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

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 ? 7z can be used to archive the contents

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:
