Sure. But do not most modern tape drives use hardware compression? All the
ones I have used, even dumb QIC tape drives that I used in 1996 have that
feature. And that surely is done on a file-at-a-time basis or even at a
block at a time basis. So who cares what software compression methods are
used unless you must read an old archive tape?
