Looking for NAS software & hardware for NT4 through and including W7
(NT4, W2K, XP and W7).

This is for an office environment doing CAD/CAM on 9 work stations that
are all currently networked. Looking for nightly backup to removable
hard drives for off site security. The 'cloud' is not a viable solution.

Manually burning CDs/DVDs just takes up too much time and is regularly
neglected so an automatic unattended solution makes sense here.

Any suggestions?

Thanks,
John
