I use pg_basebackup every day and the way I do is:
pg_basebackup -D /destination --checkpoint=fast --xlog-method=stream
The --xlog-method=stream option will copy the wal_files as well (to
pg_xlogs directory).
That works pretty well for me. You can either add the compress option too.
Hope this was helpful.

Lucas
