Connection Failure with BDRSuite Backup Server

KB ID: 101008

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

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

 Solution:

  1. Check if the BDRSuite service is running on the BDRSuite Backup Server machine:
  1. Press Win + R to open the Run dialog, type "Services.msc," and press Enter.
  2. Look for the BDRSuite 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 BDRSuite 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 BDRSuite 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 BDRSuite Backup Server and BDRSuite 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 BDRSuite 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 BDRSuite Backup Server and outgoing traffic on the BDRSuite Client.

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