I just purchased a 4TB My Book Live Duo to serve as a new disk. I previously had a 4TB My Book Studio II setup as a RAID1 and it reached capacity.
I would like to use the Live Duo as the primary external hard drive and use the Studio II as it’s backup (both in a non-RAID setup).
I can’t see how to do this with Time Machine (yes, I’m on a Mac) or with the WD Anywhere Backup or WD Smartware.
Help!
