>5. should I use the --xlog parameter and if so do I need to change wal_keep_segments from 0? you have already use --xlog as -x in your above command of pg_basebackup . yes it better to change wal_keep_segments, if you want start a postmaster directly in the extracted directory without the need to consult the log archive, thus making this a completely standalone backup.
