Earlier in the thread I suggested creating snapshots on the primary 
drive (which is something I already have implemented), to cover the 
"oops" scenario, and then the snapshots get mirrored along with 
everything else to a secondary drive to cover a more catastrophic failure.

Agreed.

But unless you are tight on storage on the primary drive, why not do both?
