For my home stuff, I'm comfortable enough with having a backup on (raid 1 mirrored spinning rust) on my media server, plus a copy of that backup (also on spinning rust) on an external USB hard drive. The chances of simultaneous corruption of those - even though they're both spinning rust - seems "low enough" for me.
(I also have another raid 1 pair of spinning rust that powers up once a week very early Monday morning and rsyncs the media server backup directory, then powers back down when it's done, to mitigate against fat-finger-fuckups and/or home network p0wnage. Somebody who p0wns something inside my network might find the cronjob or shell scripts that run the wifi powerpoint those drives use on and off, but at least I'm down to an hour or so a week where that copy might get cryptolockered...)
