4.5 Archiving and compression: tar, gzip, zip

tar -czvf site-backup.tar.gz /var/www/html      # create gzip archive (c=create z=gzip v=verbose f=file)
tar -tzvf site-backup.tar.gz                    # list contents
mkdir -p /tmp/restore
tar -xzvf site-backup.tar.gz -C /tmp/restore    # extract into a folder
tar -cJvf logs.tar.xz /var/log/nginx            # xz compression (smaller, slower)
gzip big.log            # -> big.log.gz        gunzip big.log.gz
zip -r site.zip mysite/                         # install package 'zip' if missing
unzip site.zip -d /var/www/html/                # install package 'unzip' if missing
