I have a Server 2012 R2 system which was running on 1 SSD. The server has become more important so I purchased an identical SSD to set up a SATA RAID 1 array from the UEFI BIOS.
I performed a bare-metal full system backup on the original SSD to an external USB drive using the Windows Server Backup tool and have successfully tested recovering the system to a single SSD using the method of booting from the Server 2012 DVD and choosing "Repair your computer" (before the "Install" option) and then picking the correct System Image Recovery - no problems with this procedure.
When I come to restore to my new RAID array I get no end of problems. Using the method described above, when I start the restore I get a message saying there is no suitable destination drive even though it's visible as "Disk 0" to select in the screen before hand.
If I try and install Server 2012 R2 afresh onto the RAID array, again it shows up correctly as "Disk 0" but then won't let format or partition it to continue with the install.
I eventually deleted the RAID array and re-created it using the legacy mode RAID (outside of the UEFI BIOS menu) and although I can't restore the image (I still get the "no suitable destination drive" message), I can now install Server 2012, but when I come to restore the full system using the Windows Server Backup tool it won't let me as it can see the source backup was installed from a UEFI system and the new RAID array was created from a BIOS and complains about compatibility issues!
I can't work out if this is a Server 2012 issue, a RAID / hardware issue, or a Windows Backup software issue, and no idea where to go from here! Any advice appreciated.
