> This whole madness started because someone posted an attempt at a test case for a different issue, and then that test case started failing on versions of OpenZFS that didn’t even have the feature in question. One will expect more seriosity from filesystem maintainers and serious regression testing before a release.
Periodic reminder to check if your backups are working, and if you can also restore them. It doesn't matter which file system or operating system you use, make sure to backup your stuff. In a way that's immune to ransomware as well, so not just a RAID-1/5/Z or another form of hot/warm storage (RAID is not a backup, it's an uptime/availability mechanism) but cold storage. (I snapshot and tar that snapshot every night,…
Don't have the grizzled old storage admin / DBA test the backup. They know a million and one weird necessary workarounds and just execute them. However, if you need a restore and they are currently exploring caves or something, things turn dire. Have a chipper junior restore something based off of the documentation (and prepare to spend a few days updating documentation...)
And make sure to test backup you don't regularly touch. And very much test those backups you really don't want to test.

Do you have any advice as to HOW the average home NAS user can affordably backup modern NAS devices?
The last time I looked it could easily cost hundreds of dollars per month to back up as little as 40TB to the cloud.

Also, you can probably tier your data. Maybe you don’t need same level of backup for all your 40TB.

For sensitive data I would run something else that can be a Restic target so backup data is encrypted, I currently use a cloud drive that supports WebDAV for that.

“Average home NAS user” doesn’t have 40TB of data. With a subset of data that’s important like photos it’s not that expensive and with Backblaze and other services that are directly integrated in operating systems like Synology also not that hard to do.
We have about 9TB of photos. I can easily imagine someone like us, who is into video, of having more than 40TB of videos.

My NAS has something like 5 TB used. It's all synced to an old server that can hold about 8 TB and that's off most of the time (no fun living next to a jet engine). This cold server lives at my parents' house.
My "really important stuff" on the NAS, which is a few hundred GB of pictures and such, is regularly backed up to a bucket with object locking.
My "super important stuff", which is my company's accounting and other such documents, and lives on my laptop, is backed up to the live NAS and handled there as the really important stuff. I also back up my laptop to two normally offline external drives, one of which lives in my apartment and the other at my parents' house.
Everything non-cloud is ZFS, so after each backup to an external drive or "cold NAS", I run a scrub to make sure it is still operational. The live NAS runs a scrub every Monday morning.
Granted, this is not a "modern NAS" environment, since it made no sense to me to forego the free servers that my employer was going to send to the trash and buy some expensive off-the-shelf solution without the guarantees of ZFS (despite the issue TFA talks about). I know about power usage, but my live NAS eats less than 50W at idle (which is 99% of the time), so breaking even with the electricity prices in France would take forever.

My cheap solution for large datasets is to buy a raspberry pi and external hard drive(s), setup in a friend or relatives house, and setup syncthing. One friend has a copy of my ripped discs, my parents have copies of my photos, etc. Make sure the remote instance is in read only mode.
