tar archive files usually have the file suffix .tar (e.g. somefile.tar). A tar archive file contains uncompressed byte streams of the files which it contains. To achieve archive compression, a variety of compression programs are available, such as gzip, bzip2, xz, lzip, lzma, zstd, or compress, which compress the entire tar archive.

The archive data sets created by tar contain various file system parameters, such as name, timestamps, ownership, file-access permissions, and directory organization.

If you have 16 GiB of RAM (and nothing else running), you can try: tar -cf - foo/ | xz --lzma2=dict=1536Mi,nice=273 -c - > foo.tar.xz This will need 1.5 GiB for decompression, and about 11x that for compression.

Creating compressed tar archive file in Linux using option -j : This command compresses and creates archive file less than the size of the gzip. Both compress and decompress takes more time --level=NUMBER Set dump level for created listed-incremental archive. Currently only --level=0 is meaningful: it instructs tar to truncate the snapshot file before dumping, thereby forcing a level 0 dump. -n, --seek Assume the archive is seekable. Normally tar determines automatically whether the archive can be seeked or not. This option is Similar to gzip, bzip2 also supports different level of compression, starting from 1 (default, less memory usage) to 9 (extreme compression, high memory usage).
