We want to establish trusted ssh connection between postgres@server-a and barman@server-b so that server-a can send WAL files to server-b and so that barman can on server-b trigger base backup, or launch recovery. This introduces a new architecture scenario with Barman: backup from a standby server, using rsync. To run a backup daily at 3:30, add the following line to the cron tab and save it: sudo apt-get update && sudo apt-get upgrade -y, listen_addresses = 'localhost, pgsql-backup', psql -c 'SELECT version()' -U barman -h pgsql postgres, echo "pgsql:5432:*:barman:password" >> ~/.pgpass, Now try logging into the machine, with: "ssh 'postgres@pgsql'".

However, users can manually execute the receive-wal command: Note: The receive-wal command is a foreground process. You can use Barman in geographical redundancy scenarios for better disaster recovery outcomes. This will scan all the archived WAL files and regenerate the metadata for the archive. Users are given more power: a hook script can control its workflow by specifying whether a failure is transient. The interval always ends with the current time and extends back in time for the number of days specified by the user. Important: This feature is only available for PostgreSQL 9.1 or above. But the few tutorials aren't helping that much as they're not for naive users. In such situations, users will need to manually copy the latest partial file from the server’s streaming_wals_directory of their Barman installation to the destination for recovery, making sure that the .partial suffix is removed.
