It seems the connectivity between the host machine and the BDR backup server is dropped. I think this might be due to below reasons,

  1. If 32004, 34005 ports are not listening in the host machines. You can check this by running following commands in the command prompt,

    netstat -an | find "32004"

    netstat -an | find "34005"

    If anyone of the following services is not running, you need to start the VembuIntegrationService in services.msc.

  2. Or any change in the firewall configuration. You can check the connectivity by executing the following commands in the BDR backup server and host machines.

    a. Open the command prompt with administrator permission

    b. In BDR backup server machine: telnet host_IP 42005

    c. In Host machines: telnet BDRBackupServer_IP 32004

  3. If the IP addresses of the BDR backup server or host machine might be changed. If you have configured dynamic IP addresses for the BDR backup server machine or host machines, you need to change it to static IP address.
