Thanks for your answer. This will not work for my situation. Because the hard disk of my server is failed and the only data I got are the wal files transferred to my backup server and I can only perform my recovery process with base backup and wal files stored by barman. PS: I'm trying to use a specific archive_timeout (less than 15 minutes) to see how that will affect the backup size.
