- Really? The proposal above will deal with moving stuff from a machine
- with a QIC-150-type 1/4" tape drive that can't write QIC-24 tapes to a
- machine with a QIC-24-type 1/4" tape drive that can't read QIC-150 or
- QIC-120 tapes? Neat trick!

-
- "The proposal above" seems to be "put a 'tar' or 'cpio' archive as one
- file within an ANSI-labelled tape." I fail to see how that makes things
- any better; if the problems are with variations between "cpio" and "tar"
- formats on different machines, wrapping ANSI labels around the "tar" or
- "cpio" data doesn't seem to make things any better.
-
- If the *real* fix is in the "tar'" and "cpio'" formats you list, what do
- the ANSI labels buy you other than multi-volume support?

-
- By "data" do you mean "data as opposed to programs"? If not, do any of
- the folks who have retrieved, say, the X11 source via FTP or UUCP have
- any comments on the above claim? I sucked the entire X11R3 distribution
- to our site via UUCP; I would have done the same with the X11R4 format,
- except that somebody already had it and offered to put it on 1/4" tapes
- - fortunately, a 1/4" format we can read; they put it on a "tar" tape,
- though, so ANSI tape labels contributed nothing....
-
- I suspect the amount of software moved into our site via UUCP is at
- least a significant fraction of the amount of software moved into our
- site via magtapes.
