I recall using the -f option with the - for direction to/from to move large hierarchies
around and preserve metadata including creation/modify dats, owner/group, etc.

Yeah, I just can't imagine using tar with the f option. Even back in the day when I
was writing 9 track magtapes with tar, it would be something like
tar cvfb /dev/rmt0 10 .
to get tape blocks bigger than 512 bytes. But we never had dectapes and I think they did
their own blocking.

I have no
memory of why Ken used mt1 not mt0. Doug may know.
I don't know either. Come
to think of it, I can't remember ever
using tar without option -f. Direct machine-to-machine trasfer,
e.g. by uucp, took a lot of business away from magtape soon
after tar was introduced. Incidentally, I think tar was written
by Chuck Haley or Greg Chesson, not Ken.
