Using two My Book Live NAS as redundant backups

Portable Drives My Passport
1

I have a 2TB My Book Live NAS on which I put all my important files. I fear that the drive might eventually fail so I’m thinking of purchasing another one and set it up as a mirror copy of the first.

Is there anything that would prevent having two NAS plugged on a single router?

How can I setup the second NAS to automatically mirror the first one on a regular basis?
