Raid 1/raid 5/raid 6 are about uptime. NOT about replacing a backup. What
will you do if there's a power supply surge, and your different brand
different tiem drives both go?
If your goal is 24/7 availability then RAID is a good idea.
If your goal is surviving a disk outage or other problem then it's not.
It's not a bad idea, it just won't help anything.
