ASK NC

I have a friend with a small Tax business that is wanting to use a NAS to store her information on, as well as have another backup of her data. She will possibly add another person to her business (which will make 2 people total) and was wanting a NAS for a file server and backup solution. Does this sound like the best option for her and what would you recommend? I have some experience with QNAP NASes.

Thanks you so much for your help,

Craig
