Just yesterday I was asked what NAS to recommend for home/small business network backup. I too am interested to hear what the current synopsis is.

And I suppose what backup software. They use mostly Windows, I use mostly Mac so I am not current on Windows best practices.

I lean towards RAID 1 simplicity within a NAS. Duplicated large hard drives are just not expensive these days.

Personally I prefer NAS units that run as close to silent as possible. Fan noise and unit whir are disliked.
