SG0147/SG0136: Unable to connect to the Backup Server

Vembu-VMBackup

My backup jobs fails with the error message "SG0147/SG0136: Unable to connect to the Backup Server". I checked ping to the VembuBDR server from my client machine and it ends up with success message and also I am able to access the VembuBDR server UI in my client machine. What might be the cause of this issue ? Other clients backups are connecting with out any issues to the backup server. I need this client to be backed up to the VembuBDR backup server with in this weekend. Kindly help me on this.

Did you tried logged in the server console and checked whether the backup server is running ? Since The UI will load though the server executable is not running and it can be verified by login the server console.

Check firewall configuration at server end for this kind of connectivity failures

@kristen. I am able to login the server console with out any issue. @smith_01 As mentioned in the question the backups from other clients or connecting the server with out any issues and it doesn't seems to be server level firewall issue

It seems to be a specific issue at the client level . Normally the issue might occur due to following below reasons. Please try following the below details and update in the thread

i. Confirm if the client is able to connect the Backup Server's Backup Port (default 32004) by executing

telnet <Server Name/IP Address> <Backup Port>

Example: telnet 10.x.x.x 32004

command in the VembuBDR Client system through the command prompt.

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

iii. Check that the VembuBDR services is running in your VembuBDR Server machine and the Backup Port is in LISTEN state by executing

netstat -an | find <Backup Port> [in Windows OS] (or) netstat -an | grep <Backup Port> [in Linux OS]

in VembuBDR Backup Server system.

iv. If Backup Port is not in LISTEN state, then start the VembuBDR in the Backup Server.

v. 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.

vi. 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 /conf/SGConfiguration.conf file both at client and server end.

vii. Refer the following URL to know more about NAT/Firewall configurations. nat-firewall-configuration.html

@emmanuel Thanks for the suggestion. I sort it out and noticed that this issue isdue to discrepancy in backup port and I am able to fix this issue by setting the port same at both the end
