The obvious saying springs to mind: "RAID != backup". If you need your data to be safe, have two copies of it in two geographically separate locations running in two separate machines. That's the way I treat my really important stuff (plus I keep my code in git which has sha-1 hashing of all data in it). If you need a cheapo solution with your NAS build, I recommend hooking up a pair of external eSATA/USB drives to your box with a ZFS mirror on them and do regular backups of the main NAS storage pool to it (either from a simple cron script, or using something more sophisticated, like zetaback).
