That worked for the initial transfer of that read-only file, but ne  Cfor the attempt to update it with a newer version.

    bash-3.2$ touch *
    bash-3.2$ ll

I guess that's to be expected since the man page says, in the
description of the --inplace option,

    (4) a file that does not have write permissions can not be
    updated,

That will let me do the initial backup of several more files that
happen to be read-only, but unfortunately doesn't solve the problem
in the long term.

Thanks for your help.
