Hi,
passwordless connection can be established using ssh key, and when you
don't specify the ssh key in command using -i switch:* -i
/path/to/your/private/key*
You simply need to set the SSH key as the default key which I have
explained earlier, how to do that.
As you are currently trying through following command, without specifying
an ssh key for passwordless connection.
From the EDB Postgres Advanced Server nodes
$ sudo -u enterprisedb ssh pgbackrest@backup-server
