Are you writing 'backup.tar' to tape or are you writing the backup to tape?

If you make the tarball on disk, then backup the tarball you will have to
pipe the extraction to tar to see the contents of the tarball.

If you backup the files directly to tape it's much easier to see what's on
the tape and get partial extracts.

If you have to create tarballs first for some reason, extract them and pipe
the output to the process writing content to the tape.
