Finally we will set up the transfer from the MU. What does this mean? Transfer "which channels will be sent across the network during recording, for display on the client".
That is the entire scope of what transfer means. It has no effect on the actual Storage of data on the client (assuming that local storage is enabled – the default and highly recommended setting).
Therefore, you can have multiple MU’s, each with dozens or even hundreds of channels, and transfer only a few channels – or even no channels – to the client. It will have no effect on the storage of all channels on the MU’s! This is important to understand.
Due to bandwidth limitations of any network, we recommend being prudent about transferring channels – keep the bandwidth in mind and select only those channels that you really need to see on the client in order to monitor and control the test.
In this case we will transfer all four channels. Note that all four channels are set as Yes in the Transfer setup screen:
