I don't use Raid but like everything else their is a time and place Raid is good.

This forum uses Raid. If my memory serves me right it's Raid 10 on it's server just encase a drive drops off the others will keep the forum up and running.

I have never asked John what type of backup method he uses.

I'm only a small time home user so I really don't have a need for Raid.
When I get in the mood I just do complete Backups using the built in Windows 7 backup method and to be doubly sure I also use Macrium Reflect.
I totally agree. If I were a business and needed continuous operation, I would also need a RAIDed server. I'm not, so RAID would be even more overkill than what I use now. It would also complicate keeping backups.

Many businesses farm out their data storage, maintenance, etc. to large commercial server farms. These companies, in addition to the redundancy of a RAID, also use geo-redundancy. In other words, they have multiple servers in different parts of the country or the world (cold locations, such as Iceland, are becoming popular for large, commercial servers because of all the free cooling the climate provides) and the data they are entrusted with is kept on several of those servers so, if a disaster should take out one server, the data will still be preserved on one or more other servers.
