Connection Failure with BDRShield Backup Server

KB ID: 101008

Issue:
When attempting to establish a connection with the BDRShield Backup Server, users may encounter a connection failure error. This prevents the BDRShield Client for File & Application Backup, and BDRShield Client for VMware/Hyper-V/Windows/Linux, from sending backup details to the BDRShield Backup Server, leading to backup failures.

Possible Causes:
  1. BDRShield service is not running on the BDRShield Backup Server machine.
  2. Backup Port (default 32004) in the BDRShield Backup Server is not in the LISTEN state.
  3. BDRShield Client cannot connect to the BDRShield Backup Server's Backup Port (default 32004).
  4. NAT/Firewall configurations on the BDRShield Backup Server or BDRShield Client may block port 32004.
  5. Connectivity is interrupted by an external force while the BDRShield Client agent is processing backup data to the BDRShield Backup Server.
  6. The IP address/DNS name of the BDRShield Backup Server has been modified.

 Solution:

  1. Check if the BDRShield service is running on the BDRShield Backup Server machine:
  1. Press Win + R to open the Run dialog, type "Services.msc," and press Enter.
  2. Look for the BDRShield service in the list and ensure it is running. If not, right-click and start the service

  1. Verify if the Backup Port is in the LISTEN state on the BDRShield Backup Server machine:

  1. Open a command prompt with administrative privileges.
  2. For Windows OS, execute the command: netstat -an | find "32004"
  3. For Linux OS, execute the command: netstat -an | find "34005"

  1. Confirm if the client can connect to the BDRShield Backup Server through the TCP Port (default 32004):

    • Execute the command below on the client machine's command prompt:
      telnet <server_ip_or_dns_name> 32004

      4. Check if both the BDRShield Backup Server and BDRShield Client are configured with the same Backup Port (default 32004):

    • Verify the port value in the "<vembu_installation_location>/conf/SGConfiguration.conf" file.

  1. If the BDRShield Service is running, but the telnet command fails, check NAT/Firewall settings on both machines:

    • Ensure the Backup Port (default 32004) is open for incoming traffic on the BDRShield Backup Server and outgoing traffic on the BDRShield Client.

  1. If the issue persists, it might be due to the modified IP address/DNS name of the BDRShield Backup Server.
