You still have to put the second NAS somewhere, preferably offsite to avoid the house-burns-down fail case. Personally, I don't even know where I put this second NAS, since it would need power and bandwidth, unless you really wanted to sneakernet a NAS, which would work, but seems really weird.
My home nas is small enough where I can reliably backup to some USB external drives and store in a drawer offsite. According to FreeNAS, that's a horrible solution because USB is too error prone and moving disks shortens their life, and blah blah blah, and so USB backup is explicitly a WILLNOTFIX, and a sign that the requestor is stupid, as opposed to knowing full well what the risks are, and is satisfied with them. The horrible FreeNAS community, and the lack of this feature was why I adopted OpenMediaVault. (I highly recommend OMV.)
I guess I could always upload TARs to Glacier. That might be a legitimate solution.

Think pretty much the only viable solution for this for home users
is to have a 'peering agreement' with a trusted friend where you each
colo the others machine at your home.. however this can be tricky
because you're sticking all of your sensitive stuff in someone elses
house and trading some level of full network acess to each other -
though I suppose trading access to some kind of encrypted rsync-like dumps or similar might work without some of those risks being too high
