Unfortunately, I had to disable SQL log backup for the site that was mentioned in the case because we cannot do quality of service at the moment. Fortunately we have other sites with SQL log backup, too. But they run wan connections with qos. Anyway the amount of data should be similar, so I collected log information from another site.
Did you notice the file capture_edited.txt / capture.pcapng on the old case ftp share? That was a capture of data within one 15 minutes sql log backup cycle. Please have a look at the files. In addition I uploaded a new capture and a prepared capture along with logs of the corresponding job to the new ftp folder. Additionally I informed my support engineer and he will escalate the case.
You can find servernames and ips in the case.
