Note:  With independent writer, the cache site always wins during file modifications. If files  are created at home, only metadata is transferred to the cache at the next update or  refresh. To obtain the file’s data from the home site at the cache site, use AFM’s prefetch  operation to get the data or open specific files. The data is then propagated to the cache  nodes. Figure 9-6 shows a configuration of an Asynchronous Archive Replication solution between a  home and cache site.
