It's true that whenever you use RAID you create an additional point of fault, but because RAID 1 (mirroring) allows identical content to be repopulated on its member drives, it provides a form of redundancy (which is what was intended [RAID = redundant array of inexpensive disks / independent disks]). However, as most people would say, RAID is not a substitute for a backup, so it's good to have a back up in case if your RAID array fails.

How do you setup a RAID network?

I'm not really sure what you really mean. You can set up a RAID array, but not a network that only consists of RAID. However, you can set a cluster NAS server which can utilize RAID arrays. However, RAID is never a substitute for backups, as with RAID arrays each storage device you add creates an additional point of failure - and in cases like RAID level 0 (striping), you will lose everything if even one drive fails.
