You could use the clone method. Short example below:

var Model = Backbone.Model.extend({});
var View = Backbone.View.extend({
    initialize: function() {
        this.realModel = this.model;
        this.model = this.realModel.clone();
    },
    onSave: function() {
        this.realModel.set(this.model.attributes);
    }
});

You could also do something a bit different:

var Model = Backbone.Model.extend({});
var View = Backbone.View.extend({
    initialize: function() {
        // save the attributes up front, removing references
        this._modelAttributes = _.extend({}, this.model.attributes);
    },
    onSave: function() {
        // revert to initial state.
        this.model.set(this._modelAttributes);
    }
});
