How to use Pigz with Tar

问题

So I am using pigz in tar with

tar --use-compress-program=pigz

and this works but it doesn't use all of my processors, and I'd like to make sure it's recursive (-r) and using (-9 compression level).

I read through Utilizing multi core for tar+gzip/bzip compression/decompression but it doesn't note anywhere to add additional commands in that format, and I couldn't find anything in the man page for either program for additional swithed.

Thanks, Cam

Mark Adler's top voted answer on the SO link that you included in your question does provide a solution for specifying compression-level as well as number of processors to use:

tar cf - paths-to-archive | pigz -9 -p 32 > archive.tar.gz

To pass arguments to pigz using -I or --use-compress-program, you can enclose the command and arguments in quotes, like so:

tar --use-compress-program="pigz --best --recursive" -cf archive.tar.gz YourData

Here's a fun option to monitor the speed of the archive creation:

tar --use-compress-program="pigz --best --recursive | pv" -cf archive.tar.gz YourData

fast unpack:

tar -I pigz -xf /mnt/sd/current/backup/bigbackup_web.tar.gz -C /tmp

fast pack:

tar -cf bigbackup.tar.gz -I pigz /opt

then:

apt-get install pigz

or

yum install pigz
