UPDATE: you can use the plug-in: https://github.com/berzniz/backbone.getters.setters

You can override the set method like this (add it to your models):

set: function(key, value, options) {
    // Normalize the key-value into an object
    if (_.isObject(key) || key == null) {
        attrs = key;
        options = value;
    } else {
        attrs = {};
        attrs[key] = value;
    }

    // Go over all the set attributes and make your changes
    for (attr in attrs) {
        if (attr == 'name') {
            attrs['name'] = attrs['name'].toLowerCase();
        }
    }

    return Backbone.Model.prototype.set.call(this, attrs, options);
}
