Use the fields on the General tab to describe the general properties of the Barman server:

  • Use the Name field to specify a user-friendly name for the server. The name identifies the server in the browser tree.

  • Use the URL field to specify the URL of the host where Barman is installed.

  • Use the Team field to specify a PostgreSQL role name. Only PEM users who are members of this role, who created the server initially, or have superuser privileges on the PEM server will see this server when they log on to PEM. If this field is left blank, all PEM users see the server.
