Recover DeDuped Recovery Points

After sorting out an incredible mess Storage Spaces seems to be well known for when a physical drive takes a crap I am now in what almost feels like deeper doo doo!! Ive been using DPM 2012 R2 Version 4.2.1254.0 for quite some time. The Server with the Storage Spaces mess is a 2012 R2 OS as well. To add to the fun I had had dedupe turned on the Server being backed up. The DPM Server seems to have all the backups which would be 3 recovery points per day with 5 days retention and no tapes. I am able to do the Recovery both to "original location" and to Network Location. However, as YOU would know "original location" produces an error about missing volume: \\ ?\Volume{6460399a-ef18-4e02-90a5db1ebaf20962}\ . So I tried to restore it to the Network Location and use the "missing or crashed" volume that has been deleted and recreated/rebuilt in Storage Spaces. I get a conglomeration of folders which looks like the info needs to "restore or rehydrate" the deduped data but Ill be switched if I can get it to work. Ive attached a screenshot of the file structure DPM Recovery puts on the recreated volume V:\ on Destination Server if that might be of any help.

Storage Spaces, Deduplication, DPM: am I NUTS??!!! What happened to the old days .bkf??? Any help, articles or direction to head to would sure be appreciated..   The bottom line here is the recovery points all contain 465 +/-Gb in size which is correct, however, when DPM lays it back out either in the newly created Volume on the original Server OR another location it is conglomeration of files that appear to need hydration.

Mike, THANKS for this and THANK for all you do in this forum; I've talked to you about other Twilight Zone episodes I seem to have on a regular basis!! I'm going to try to restore to a fresh formatted 4Tb drive WITHOUT Storage Spaces and WITHOUT DeDupe of course I'll probably get the message about non-DeDupe aware volume. I will probably even try the manual Restore methodology witch has really scanty amounts of "how-to" information on it as well(not well documented or at least 2yrs. ago when I tried it). The size of the Backup on DPM is correct at around 465Gb so its gotta work somehow. You can see many files under the Data folder in the screenshot they are just not being put back together. There are just too many "new" technologies at play here with Storage Spaces being the worst culprit and then I was bold enough to go for "thin provisioning" as well!!

I'm assuming you were talking about a $295 an hour support ticket which isn't going to happen in my small company!! THANKS again for everything!!
