okay. Could you please provide me some details about the backup size?
How much free disk space do you have on the target? You need minimum 6GB free space to store all the zip files.
How did you enter the ip of the server into the RS-monitor?Did you entered it with port 3344?
Is it only with the big file selected that it fails? In that case, please use the manual method for it. I can not say why it fails. Will try to create such a big file for tests and see if I can reproduce for a future version. There is no known size limit in this configuration, but apparently it fails. So either your network is having errors in the time it takes to upload or there is a unknown limit problem.
Ok so glad it now is updated also manually. There is no log for this problem I think. I have now a 2gb sample so hope I can reproduce with it later. I think it is most likely a timeout from the file being not uploaded in an expected time.
