cement board is not necessary for a back splash unless it is an extremley messy cook. In a commercial kitchen maybe but not a residential kitchen. It will need to be re-sealed every few years but for stain resistance not necessarily water permiation.
Cement board is absolutely necessary for showers and very wet applications as most grout will absorb some moisture and it will eventually have small hairline cracks that you can't see but will allow water through.
