To begin, you will need the following packages installed:
tar
pigz
pv (optional)
Compressing with pigz can be done a couple of different ways:
tar --use-compression-program=pigz -cf yourfile.tar.gz folder1
tar cf - Pictures/ | pigz > pictures.tar.gz
These commands can also be piped to the "pv" program to monitor the progress of the compression.
tar cf - Pictures/ | pigz > pictures.tar.gz | pv
