Ok, raise your hand if you are using RAID as a backup. No, seriously.
Those with your hands up … have you ever lost data? Want to?
Keep using RAID as a backup.
I don’t mean disk to disk backup. I mean not using a backup when you have a RAID. The RAID is your backup.
What is the cost to replace all the material you have created over time stored on that RAID? What is its value? If its larger than the cost of the disks, you could duplicate the storage and reduce risk
Seriously … take a USB2 drive, attach it to your servers, and make copies of important things.
I don’t like it when users get angry over lost data that they could have prevented.
