    We have one old Apollo 420 and plan to get several
    3000s before fall.  Our 9-track tape drives, however,
    will be connected to our central Sequent Symmetry.  So I
    asked the local Apollo rep if he knew of small programs
    to convert formats from tar to wbak and back...

That would be tough.  The formats don't contain the same information
(tar tapes lack acls and file type info, wbak lacks owner and mode
info).

If you install sr10, you can at least write wbak to stdout and read
stdin into rbak, which in theory makes it possible to remote your
backups to the Sequent.

Also, the sr10 tar has an option to write out acls and type info,
but this info wouldn't be understood by another unix system, of
course (it just gets ignored).

I always just use tar for backups, since I don't care about acls
and don't keep very many files of odd types around.
