How do I backup my file system with tar and multi-thread?
I would like to backup my file system and do it with parallel. I found this guide: https://help.ubuntu.com/community/BackupYourSystem/TAR
Where they give me the command:
tar -cvpzf backup.tar.gz --exclude=/backup.tar.gz --one-file-system /
I found that I should put -I pigz in the beginning of the command, however this gives me the error:
tar: Conflicting compression options
How can this be solved?

With the modification, it's your conflicting command looks like this:tar -I pigz -cvpzf backup.tar.gz --exclude=/backup.tar.gz --one-file-system /?

The z flag you have in your command means:
-z, --gzip, --gunzip, --ungzip
Filter the archive through gzip(1).
So if you then use -I which means:
-I, --use-compress-program=COMMAND
Filter data through COMMAND. It must accept the -d option, for decompression.
The argument can contain command line options.
Then you are telling it to use both gzip and pigz, so it complains because you've given it conflicting compression options. So just remove the z:
tar -cvf backup.tar.gz -I pigz --exclude=/backup.tar.gz --one-file-system /
Note that I also removed the -p since that shouldn't have any effect when creating an archive:
-p, --preserve-permissions, --same-permissions
extract information about file permissions (default for superuser)
You should use that when extracting, not when creating the archive.
