Bottleneck

Both backup and restore are technically demanding. Via various steps (agents, file system, network), the server must deliver a constant data stream to the streamer so that it can write data to a band with minimum speed. A cache in the streamer as well as variable band speeds see to balancing speed fluctuations in the data stream. Aim is to remove bottlenecks in the dataflow to the streamer in order to prevent an accelerated wareout.
