Hi John! Thanks for answer, sorry for long delay. We do not use encryption and compression as well. We backup to filestorage. The storage device is directly attached to the bacula-sd (director and sd is on the same machine). SD is on the same network (gigabit LAN) as the client. How can I debug windows file daemon?
