I'm not concerned with the http server method... It's more getting the data from jsdom or an alternative method at this point.

Looking at the docs, instead of passing an object literal to jsdom.env, pass arguments.
First you'll want to get the html contents via fs.readFileSync('dir/backup.html', 'utf-8')

var htmlSource = fs.readFileSync("some/dir/backup.html", "utf8");
jsdom.evn(
    htmlSource,
    ['array', 'of', 'scripts'],
    function(window){

    }
);

Looks like you could also use the object literal config and use the file property.
e.g.

jsdom.env({
   file: '/path/to/backup.html',
   ...

I'm not 100% sure, but it looks like the file might not be populated by the time jsdom is called.
If that's the case, you could remove the use of pipe, and instead use fs.writeFileSync

Thanks Jason I got it working. For now I'm using fs.readFileSync method. I was also missing:

The jsdom.jsdom method.

var jsdom = require("jsdom");

Needed to be:

var jsdom = require("jsdom").jsdom;

This allowed the window callback to load the file. Previously I was getting the file in the error cb.

var fs = require('fs')
  , jsdom = require('jsdom').jsdom;

var htmlSource = fs.readFileSync(__dirname + "/date.html", "utf8")
  , document = jsdom(htmlSource)
  , window = document.parentWindow;

console.log(typeof window.document.getElementsByClassName); //function
console.log(window.document.getElementsByTagName('a')[1].innerHTML); //logs link text "311.json"
