as stated several times WHS back up wont back up this 3TB volume hence why I got 2 drives and mirrored them.
Mirroring is not backup! It's simply hardware redundancy. Backup is having multiple copies of your data that are independent of each other and mirror isn't, strictly speaking, that at all. You need to be using something like robocopy (has a very nice and effective syncronize switch) or the free version of CrashPlan to make real backup copies of your files. But mirroring is not an adequate backup strategy at all.
