In their jargon it’s called “scrub”. There are different arrangements, I have 3 disks under raid 5 or raidz 1. Data is written twice and every month I confirm checksums.

In the past I had lost photos on faulty disks, this solution provides me with techniques for coping and dealing in such scenarios.

True. But you can save photos and videos under self-healing filesystem like zfs. Is far more cheaper than a year of multiple premium subscriptions (google, netflix, spotify). And it’s not recurring monthly other than electricity bill…

immaterial then, but space opera nonetheless.

And, chelsea manning. I’d love to see more whistleblowers in the world. That’s the kind of mass sousveillance we need!
