Cloning to two backup drives or is one good enough?
My goal was to have the 3rd 8TB drive back up off the main 8TB drive and the 3rd 4TB drive to back up off the main 4TB drive. So basically both the main 4TB and 8TB drives would clone themselves to two drives each. Is this over kill and a waste of money on extra drives not needed? My 8TB's are used for my business and my 4TB's are used for my personal stuff.
Because what are the chances two hard drives (main and backup) fail at the same time? I mean if the main drive of either my 8TB or 4TB fails, then I can just go buy another, and clone the new drive from the backup. But I am wondering if I should keep the third set of drives or return them? It's still $300cdn for both, a good chunk of money.
Keep them or return them?
