Hi HÃ¥var
Unfortunately there is not a way to disable the upload of the backups. The upload should not be occurring. As per my answer above, this is a bug, that we have made a fix for, and will release a new build as soon as possible.
You can however move the backup created daily, to a different folder. This will prevent the server attempting the upload as it will not find anything. This will have to be done each time a backup is created in the folder chosen for backups.
