K42.7z ✦ Tested & Working

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

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

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 such as /dev/sda1

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 ?
