Running BE16 to backup a Hyper-V-Cluster starts with good performance, creates the avhdx (full backup) and after 20 minutes is down to 500 MB/sec. Cant cancel the job from the console, have to stop serrvices. Disk are connected over fibre-channel.
Searching for causes i found the HF and was thinking it should be included in FP1 which i installed already. Nevertheless i could install the HF over FP1 and it showed message HF successfully installed, that's a very strange behaviour.
