Hi , Trying to get my understanding correct . I have 2 x 3 TB drives and If I was to raid the device it will mean that I have a mirror copy of what is on the 1st 3Tb drive on the 2nd 3tb Drive. Correct. As such the I do not need to have back up software as such. If I back up from my PC HDD with back up software to the Live DUO that is in RAID then it is backed up again as a mirror!
Does all this make sense?
