That is correct. You have the option to use the "Normal" copy which uses SMB. In that case, nothing needs to be installed on the destination.
If you have millions of small files or copying across WAN connections, then you could explore the enterprise edition which offers another method to copy files using TCP Copy which in turn would require a lightweight agent to be installed on the destination. In this scenario, files would be copied over a single TCP port (configurable). TCP copy has proven to be more advantageous over SMB when copying millions of small files or when copying over WAN connections where latency could hinder the performance of SMB protocol.
