Windows Server Backup Recovery Fail – A Handle to the driver control device could not be created. . .

We needed to spot recover some files on one of our client’s servers.

But, when we plugged in the required backup USB hard drive and ran the Recovery Wizard from within the Windows Server Backup (WSB) node we ran into a really strange error:


Recovery Wizard

Unable to browse ServerName (C:). A handle to the driver control device could not be created. Make sure the driver is installed correctly.

Now, a search for the error message turned up very little in the way of results.

Somehow, in the numerous searches we attempted on the problem, the following site held the clue:

In the above linked forum post SriramB[MSFT] runs the questioner through some steps to get WSB installed. But, the clue for us was found because of the following found in the Device Manager after revealing hidden devices:


We right clicked on the File as Volume Driver and Uninstalled it. We then right clicked on the root computer name and clicked on Scan for hardware changes and the File as Volume Driver got picked up:


File as Volume Driver

Device driver software installed successfully.

Once the driver was installed, we saw this in our Recovery process:

image The + NetworkData (L:) volume was able to be browsed for the content we were looking to restore.

We are not entirely sure what caused the driver to get knocked out in the first place since the backup portion of WSB was working just fine.

This is one reason why regular spot recovery as well as a full recovery tests should be a mandatory part of any managed services offering. If the backups are not tested, then no one will know they were broken until there was a real emergency.

Lol, I'm the guy who had the problem getting backup installed and posted in the technet forum. Glad I helped someone as I only resolved that issue by a full re-os. :(
