WAL logs multiplexing?

Hi,

I'm currently considering setting up online backup procedure and I
thought maybe it would be a useful feature if the online logs could be
written into more than one place (something like oracle redo logs
multiplexing).

If I got it right if the server's filesystem crashes completely then the
changes that haven't gone into an archived log will be lost. If the logs
are written into more than one place the loss could be minimal.

Best regards,
