What I have done in a situation like this is to have the archive
command copy to a directory on the database server machine, and use
rsync to make copies on all targets. If you try to have the
archive command deal with both standby machines directly, it gets
pretty complicated trying to handle the failure of one of those
standby machines, or of the network connecting to one of them.
