The main difference is that you have to stop the server if you want to use "rsync",
otherwise the backup will be inconsistent.
A backup taken with "pg_basebackup" will be recovered when you start it.
You *can* perform an online file system backup with "rsync", but then you will
have to use the low-level backup API:
