tar as invoked with c above won't delete or change the files it's turning into
a compressed tarball.

Not really.

Unnecessary. Try creating a tarball on a dir with some files you don't care
about and see.

Appending files to a compressed tar file probably won't do what you want.
Remember that tar was originally a TapeARchiver , and tapes aren't seekable in
the way disks are, and the way it works makes a bit more sense. If you want
to make a compressed archive and change it often, zip would probably be easier
than tar.
