My cheap anonymous USB cable is bit perfect when used to backup my harddisk (thankfully as I was recently forced to discover) and at data rates far higher than that needed for audio. Since the Synergistic Research USB cable sounds different to my cheap reliable cable will it corrupt my computer data if used for backups?

  Backups are not "real-time" so the cables will have the same result, no data errors. Streaming audio is a different case, real-time.

    I am not sure I understand how streaming audio differs from streaming data for USB devices. As I understand it, my USB sound card has a small buffer which is filled with audio samples passed across the USB cable and the size of the buffer is related to the size of the latency that is often quoted. This buffer would seem to need data at a rate of 1.4 Mbits per second (2 channels of 16 bit samples at 44.1kHz) across a USB 2 cable with a speed of 480 Mbits per second. There would not appear to be a problem keeping the buffer full enough or is there?
