I just migrated to a new computer, but was unable to open/restore old backups. I had to enable automount in diskpart and uninstall the Home Server Restore Driver as found here:

"Finally found the solution. I've been struggling with this for a year. just go into your device manager on your client and expand the system devices tree and uninstall any Home Server Restore Driver you see. Reboot if necessary then you should be able to mount your backup. "

I did not need to reboot.

JSON is a powerful way to transmit or expose sets of data to jQuery or javascript. There are several api's such as twitter, flicker, and yahoo that allow this functionality. Unfortunately, it can be used for bad intentions. To curtail such experiences, a "defense system" for foreign requests was created. This defense places restrictions on requests that occur on cross-domain http requests via javascript for returning data in the JSON format.

For visualization:

To bypass this issue and reduce the opportunity for accidental exposure of vulnerabilites, you have to change the response type of requests for this scenario. In jQuery 1.2, JSONP support was introduced. Jsonp, or JSON with Padding, is a a way to wrap json responses in callback manner, and remove client side get requests allowing only posts.

Using MVC, you can easily expose JSON responses with your Controller. A simple way is to return a JsonResult. To add JSONP functionality, however, you will have to create a custom class, or extend the existing JsonResult.

Changing something like this: {"Id" : 4, "Name" : "Matt Linder"}
to this:
callback({"Id" : 4, "Name" : "Matt Linder"});

I have implemented a default callback on the originating server, with the option to specify a custom consumer script for the callback, which seems to work well.
