The nbpgsql.conf configuration file

The NetBackup for PostgreSQL configuration (nbpgsql.conf) file is contains the parameters that you must specify for the respective operations. It contains predefined settings and is located on the client. When parameters are not configured in the nbpgsql.conf file, then the default parameter value takes precedence. You can configure the parameters in the nbpgsql.conf file or set them on the command line, where the command line parameters take precedence. The nbpgsql.conf file keeps you from providing the parameters every time you run operations.

The nbpgsql.conf file is located in the following locations:

  • (Windows)

    install_path\NBPostgreSQLAgent_8.1_AMD64\nbpgsql.conf .

  • (Linux RHEL) install_path/NBPostgreSQLAgent_8.1_linuxR_x86/nbpgsql.conf

  • (Linux SUSE) install_path/NBPostgreSQLAgent_8.1_linuxS_x86/nbpgsql.conf
