There are about thousan comment to use raid as your backup technology. If my data s important to me, I would pick a tape drive, and then keep data for as long as 7 to 30 years. Optical media, one scratch and data is gone.
nowI should get response for Nearline storage, but people, the guy wants some thng for 200G and retain it for some time. so look into future growth also, setting up raid is NOT backup. if you delete a file by mistake or overwrite a file, RAID does not save for there.
