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: https://www.postgresql.org/docs/current/continuous-archiving.html#BACKUP-LOWLEVEL-BASE-BACKUP Yours, Laurenz Albe
