Bacula Client Behind NAT Support with the Connect To Director Directive

A Client can now initiate a connection to the Director (permanently or scheduled) to let the Director connect back when a new Job is started or a bconsole command such as status client or estimate is issued.

This new network configuration option is particularly useful for Clients that are not directly reachable by the Director.

# cat /opt/bacula/etc/bacula-fd.conf
Director {
  Name = bac-dir
  Password = aigh3wu7oothieb4geeph3noo  # Password used to connect

  # New directives
  Address = bac-dir.mycompany.com       # Director address to connect
  Connect To Director = yes                  # FD will call the Director
}


# cat /opt/bacula/etc/bacula-dir.conf
Client {
  Name = bac-fd
  Password = aigh3wu7oothieb4geeph3noo

  # New directive
  Allow FD Connections = yes
}

Attention! The Client name in the Director’s configuration must be exactly the same as the one configured in bacula-fd.conf.

It is possible to schedule the Client connenction to certain periods of the day:

# cat /opt/bacula/etc/bacula-fd.conf
Director {
  Name = bac-dir
  Password = aigh3wu7oothieb4geeph3noo  # Password used to connect

  # New directives
  Address = bac-dir.mycompany.com       # Director address to connect
  Connect To Director = yes             # FD will call the Director
  Schedule = WorkingHours
}

Schedule {
  Name = WorkingHours
  # Connect the Director between 12:00 and 14:00
  Connect = MaxConnectTime=2h on mon-fri at 12:00
}

Note that in the current version, if the File Daemon is started after 12:00, the next connection to the Director will occur at 12:00 the next day.

A Job can be scheduled in the Director around 12:00, and if the Client is connected, the Job will be executed as if the Client was reachable from the Director.
