Backup and Recovery of Deduplication Windows Server 2012 Volumes

I currently run Avamar 7.0.1-61 and have happened upon a major issue.  Upon finding the issue as it is described in the article in the link we thought installing the hotfix would resolve the problem but in testing we still have the same issue.

Problem:

1.  We have a Windows Server 2012 machine that we have de-duplication turned on.

2.  We create a policy that backs up this server with the "Perform a Windows Optimized Backup of a Windows Deduplicated volume" checked.

3.  We recover the data to another server that also has de-duplication turned on as documentation explains we must and we have a large number of corrupt files.

First attempt at solution:

1.  We read the article in the link above and deploy the hotfix to all machines that we have de-duplication turned on.

2.  We allow new backups to be created after having the hotfix installed.

3.  We attempt to recover the data to the same second server (again that also has de-dup configured) and we are still unable to open files because of corruption.

Thoughts

The article in the link explains that in order to recover files that the entire volume would have to be recovered to get a reliable restore.  I would love to do this to prove that the backups are actually reliable but recovering 2TB isn't something I feel like doing.

Does anyone have experience with this issue?  Does this mean that file level recovery on all de-duplicated Windows Server 2012 backups are doomed?  I currently have an SR for this issue...but considering that most people are happily backing up their de-duplicated volumes without any knowledge of the struggles if they were ever to recover...I thought I would post this.
