SBS 2008 Restore from Windows RAID to HP DL380 P410i hardware RAID?

Last Modified: 2012-08-19
I have a HP ML series server with five 76.8GB physical drives showing up in Windows Server 2008's disk management. Two of them form a mirrored system (C) drive, and the three other form a RAID 5 D: drive.

One of the drives is showing errors, and for a variety of other reasons, I am tasked with replacing that server with new DL380G7 hardware, with a P410i RAID card.

I have only SBS Backup on the server (no third party software), and want to use it to perform a bare metal restore.

My understanding of the Windows Server Backup is that I need the same number of drives, of the same of larger size as the original original ones.

HOWEVER, I want to restore from Windows RAID/Mirrors onto the hardware RAID, where Windows will see only two physical drives, one of 300GB and the other of 500GB. Both of these drives are bigger than both of the other logical drives in use today.

I understand that Windows Server Backup is concerned with the size of the partitions/volumes - NOT the amount of used space they have on them.

Even when I set up the array with 2 drives exposed to Windows, and attempt to restore only the C drive, it does not work - it says the drive is not large enough and asks me to add more/larger drives. In this example, the two physical drives available in the 'Exclude Drive' box were the two RAID drives on the P410i, and were 300GB and 500GB in size, where as the C drive has only two physical drives less than 100GB each in a mirror. I would expect that restore to set up a mirror on those two physical drives. (I have not tried making two logical drives of identical size).

The system is still up and running, so I am considering using a more flexible backup/restore product such as Shadow Protect.

Does anyone know if it is possible, using the command line backup utility, to execute a restore from a RAID done by Windows to a RAID done by hardware?

Otherwise, does anyone know a suitable backup product to use to allow me to do this?
