"permanent" backup solution

Hi Zone8,

My NAS is really good (I mean I like it).  It does a lot of things:

- connected to my gigabit network;

- it is 2 x 1TB drive mirrored, so has a lot of data security;

- I had shared a couple of folders on my old pc which the NAS would automatically backup every week, with advanced features such as compare files and keep the latest, etc;

- I have my photo website running on it, accessible from anywhere (simple but easy to share photos with people);

- streams videos, music and photos to my TV, tablet and phone (only within my network);
