Backups will fail with above error message for the following reasons:

  • Backup agent is not able to connect to the Backup Server's Backup Port (default 32004).
  • Vembu BDR is not started in the server machine, therefore Backup Port (default 32004) is not in listen state.
  • NAT/Firewall configurations in the backup server which may block 32004 port.
  • The connection between a client and the Backup Server is closed prematurely by an external force, while the client agent is actively processing the backup data to the Backup Server


  • Confirm if the client is able to connect to the Backup Server's Backup Port (default 32004) by executing the telnet command ('telnet ServerIPAddress 32004') in the Client machine through the command prompt.

  • If the telnet command doesn't work, then check the firewall configuration of the Vembu BDR Server and make sure the Backup Port (default 32004) is open for the incoming traffic.

  • Check if the Vembu BDR service running in your Server machine and the Backup Port is in LISTEN state by executing “netstat -an | find 32004” [in Windows OS] or “netstat -an | grep 32004” [in Linux OS] in Vembu BDR Backup Server system.

  • If the Backup Port is in LISTEN state and telnet command fails, make sure the Backup Port is open in the Backup Server network's NAT/Firewall settings.

  • Also confirm that both the backup server and the client are configured with the same Backup Port (by default, the port should be 32004). Verify this by checking the "Vembu Installation Location>/conf/SGConfiguration.conf file."
