I was reading online that RAID1 is not a very reliable backup method, and is primarily for speedy recovery, over true reliability. I want to buy a dual-bay enclosure; something like the Icy Dock MB662UEAB-2S; http://www.icydock.com/product/mb662ueab-2s.html People say they the best thing to do is get 2 separate external drives and backup with one, and use the other to make a copy of the backup drive, so you have 2 separate drives. Would it be fine to just to put 2x1TB drives into the enclosure, setup as JBOD then use Superduper to clone drive A onto drive B. Or is this not a good idea. Also can I stick a single drive into the IcyDock now and buy a second one later, as im a little shot of money at them moment. I got a 500GB old schol hardrive i could use for redundancy for the next 6 months, before i add a second drive into the enclosure.
