Hi Pcawley.

The error "Backup Request Failed for Backup [Files] to server. Failed while reconnecting - Error - no backup session available." if the client try to reconnect the backup server, but the session between the backup server and client has been expired.

During the backup process, if any socket drop happen client will try to reconnect the socket and backup server keep the backup session, so that once the client reconnect the backup server successfully the backup will resume uploading the data to the backup server. If the re-connection doesn't happen for 3 minutes the backup server will terminate the backup session and if the client reconnect the backup server successfully after 3 minutes then the backup will end up with the above error message.

To over come this case, please increase the re-connection time out values in both backup server and your client machine. Please follow the below steps to increase the time out value.

1. Stop Vembu BDR in your backup server and stop Vembu NetworkBackup in your client machine.
2. Edit 'SGConfiguration.conf' file from location '<vembu_home\conf>' in the text editor.
3. Change the attribute ServerReconnectTimeOut="600" from the <module> tag.
4. Change the attribute ClientReconnectTimeOut="600" from the <module> tag.
5. Save the file and start Vembu BDR in your backup server and Vembu NetworkBackup in your client machine.

Note: you need to change the re-connection time out values in both backup server and also in your client machine.
