I need to be able to create working copies of drives that are setup in a raid configuration and be able to use the copies to boot the system in a raid configuration. This would mainly pertain to a Windows Server based OS.

I still don't see a Question here. If you setup RAID 1 for example, you have two mirrored disks. One of them fails, the other is still there and there is no down-time. That is what RAID is for. 1 disk (or more depending on what RAID level you are using) can fail and the system will keep on working. You then just need to replace the failed disk with a fresh one and the array will rebuild without down-time.

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

I want to reload the server but before I do I want to have a bootable copy that can be used to restore the server if needed.

Then just make a backup. Or you can also remove one of the disks from the array. and you can then just remove all the disks and put back the one you removed, and it should boot (depending on the controller, you may have to import the disk, ot if you are using OS software RAID, you just need to set the BIOS to boot from this disk).

Would I need to rebuild the raid?

It depends. If both disks in the array are unchanged, and you insert them again at the same time, chances are the array will work fine. But it also depends on the controller. Rebuilding a RAID 1 array is usually not much of a problem though, and a backup is essential anyway, so should something fail you can always restore from your backup.

Will the backup included with Server 2012 do this? I use it but have never had to restore completely using this product.

If the backup is good, yes. But 3rd party backup software is generally easier to use and offers more features.

Thanks for the advice. I have replaced several failed drives in raid configurations and was familiar with that but not keeping the old while I started clean.
