What you might be thinking of is the "old" method of doing base backups
before pg_basebackup:  Call pg_start_backup() and then do file system
operations (tar, scp, whatever) to move the data files to where you want
them.  This is mostly obsolete.  You should run pg_basebackup on the
host where you want to set up your standby.
