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. K42.7z
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 can be used to archive the contents
Information on into smaller parts? Let me know which direction helps you most. such as /dev/sda1
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?
