(GNU tar) the old original tar in FreeBSD was gtar, then they renamed tar to gtar, and added in a BSD tar (that is unencumbered code) man gtar should tell all you need. Also a note on your 8MM, 14gb compression is a salesman's fantasy. I think they use test files that must contain 100,000 binary 1's to get those numbers. Your more realistic to expect about 10GB with the tape hardware compression or even 9GB. Also, files like mp3's and jpgs are already compressed so you gain nothing with hardware compression on those.
