“You're weak on logic, that's the trouble with you. You're like the guy in the story who was caught in a sudden shower and Who ran to a grove of trees and got under one. He wasn't worried, you see, because he figured when one tree got wet through, he would just get under another one."
One of my all time favorites. Though it took me a while to remember the source of the quote. I thought it had been used in the context of global warming so google didn’t turn up much. Then I remembered it’s actually from a story about universal cooling.
That's incorrect. RAID is a system build on top of hard drives for redundancy. Redundancy (for this use of the word) is simply duplication across multiple hard-drives, which doesn't require a system at all.
Really, this is a very simplistic view of long term storage.
A RAID is not magically more reliable than a single drive, it needs a bunch of infrastructure and it needs to be duplicated to some other location far away enough to ensure that a single catastrophe such as a fire does not destroy your entire raid.
You are missing the wood for the trees: hard drives and raid devices are storage mechanisms that fall far short of the boundary conditions set to keep something permanently, at worst you will store your data for a couple of hour like that and in ideal conditions maybe for a couple of years, but on a scale of decades or centuries they are useless as a complete solution, though they could be part of such a solution.

Huh, I don't think I've seen a reference to that story in years, but just emailed it to a coworker a couple hours ago.

That's not a hard drive. That's a system built on top of hard drives.
And so is perkeep.

Just saying to yourself "I save all my stuff on two drives" is a system. It's just kind of a crappy one that's really prone to failure.
redundancy is not helpful if your system consistently fails after some regular interval
