RAID 0 is the best way to ensure data redundancy. It's what we use at every Fortune500 company and there's not an issue.
But it's still not a backup strategy. You should always have a second partition on the server that you sync your data over to. For performance reasons this partition should be on the same RAID 0 array.
Preferably something geographically separated from the server as well in case of some kind of physically destructive event like a fire.
Most people don't know this but RAID6 is also a fire deterrent
It also is excellent at keeping out ants.
You rarely see ants in datacenters and its because of all the RAID.
