I found my answer finally from a PowerBiz Solutions article on the internet. The problem was described as being caused by having installed the NTBackup Restore Utility for Windows 7 and leaving it installed after migrating a Server from SBS2003 to SBS2011 as I had done.  It further explains that any future backups including BMR will not include contents of a specific folder c:\Windows\Registration if this condition exists.  The solution was simply to copy these files from the working server over onto a USB and then copying them into the same directory on the "recovered" server.  I did this and rebooted and the System came up fine, recovered to similar hardware on a different machine.  I believe the only thing I have to do now is remove the utility from the production server so the backups will be complete going forward. Hopefully others in the same situation can benefit from this information I was so fortunate to run across. Also, I think the drive letter assignments was never an issue in my case. I believe they were temporary assignment for the recovery environment, so naturally any changes I made would disappear upon reboot as I was no longer in that environment. -Patrick
I am testing for disaster recovery for our T610 server. I have a second similar T610 server and using the SBS 2011 media and a Windows Server BMR backup from the production server attempted to restore to the "testing" server. Both have the same PERC Raid cards and I configured the second server to contain the same RAID 1 (os) and RAID 5 (Data) Virtual drives. I have gone thru the recovery process a few times. First I did it without installing any drivers and after restoring (and before rebooting) the system came up with the drive letters incorrect (system reserved was C: and the OS and Data drives were something like D: and E:). Before rebooting the restored computer I used diskpart to reassign drive letters (removing the drive letter from system reserved and assigning it as active in the process).  When I booted the system after removing the DVD it would only allow me to go into the repair mode ("start normally" fails). Also, once in repair mode the drives are back to what they were before i changed them. I can change them again, but when I reboot they change back again, same scenario.   So, for the next try, I used the same procedure, but in addition to above, i added the PERC drivers during the process.  The behavior was the same except in this case the system reserved drive showed up in diskpart without a drive letter. But, after changing the other drive letters and rebooting, system reserved now has C; and the other drives have once again reverted to "incorrect" drive letters. And I still have a none restored system.  Each restore attempt take several hours due to the amount of data, so any guidance is greatly appreciated. Also, I did a check of the Production server and believe both systems are using BIOS rather than EUFI. Sincerely, Patrick
