On Win 2012 r2 from few weeks i have a strange issue.
Every second backup end after about 1 minute with message "more data is available"
Reconfigured backup from scratch - the same error. Reformatted usb disk - no change.
I've no idea. I can't find any valuable info in logs. When i start backup manually from console - everything is ok.
Server is up to date, restarted. Nothing helps.
Maybe someone can help ?
