tar is a program for creating archives.
tar archives, or tarballs, preserve unix permissions of multiple files or folders.
By default, a .tar file is not compressed. Typically you'll see .tar.gz, or .tgz which denotes a tar file compressed using gzip.

Getting Started

Extraction

tar xzvf archive.tar.gz

Archive

tar czpvf archive.tar.gz files

Flags

-x extract preserving paths
-p preserve permissions
-c create an archive
-f specify file
-C output dir

Compression formats

-z use gzip
-j use bzip2
-J use xz
-I pigz use pigz (parallel gz)

Progress Bar

Reference

Tar does not provide a progress bar.
You can get a progress bar by piping tar through pv:

tar cf - $folder | pv -s $(du -sb $folder | awk '{print $1}') | pigz > $folder.tar.gz
