I have a Hyper-V host with 4 physical HDDs, 300 GB each, and this machine will host a couple of VMs, each probably with a size of approximately 150GB.
The VMs are not mission critical but I still need some kind of protection against HDD failure and would rather avoid RAID (please accept that I would rather find a software solution, for various reasons). First I was thinking of a setup like:
HDD 1: VM A full image backup of VM B HDD 2: VM B full image backup of VM A etc.
So if disk 1 fails, I can recover both machines from disk 2, and vice versa.
However, that feels very "manual" and I also need to have VMs of the proper size - e.g., if VMs grew to 200GB, this strategy would break down.
If the box was Windows 8 Server with the new "Storage Spaces" feature, I would almost certainly go for that (at least it sounds ideal for my scenario).
But in this pre-Windows 8 time, what do people use on Windows Server 2008 R2? Is there some built-in service that provides something like Storage Spaces today? Can 3rd party utilities like Drive Bender provide this functionality? Are they proven and reliable?
