But why exactly is Vahz, the dark mascot, setting all of this up for?

Entropy.

Chrono Crusade is maybe the closest you’ll get

Chrono Crusade is a Miko x Yokai adventure story except the Miko is a Nun and the Yokai is a “Demon”.

Mikos are known to use archery to defeat Yokai. No wait, its a nun and westerners use guns, right? And they meet all kinds of Yokai… like good yokai, bad yokai, friendly yokai. No wait, western culture doesn’t have Yokai, they call them Demons. So good demons, bad demons, friendly demons…

Nothing wrong with that :-) Switching up the setting is fine but its not especially “Christian” in theme.

You expect a country of Buddhists and Shinto to make a Christian anime?

There’s Evangelion, which is closer to how we Westerners take Buddhist holy texts and say random techno-mumbo-jumbo in our SciFi stories (ex: Stargate).

Similarly, Angel Beats takes the Christian idea of Purgatory except it’s all Buddhist / Zen enlightenment based because Japan doesn’t get Christianity lol.

There is Death Note, where some characters are explicitly Catholic and a few Christian references pop up kind of elegantly. (L washes the feet of Light Yagami for example). I wouldn’t call the plot especially ‘Christian’ otherwise but this does deserve mention as an Anime that at least got the meaning behind the Christian references they chose.

Digimon Season 1 might be the closest thing to Christian. Kids get powers as they invoke the power of Virtues like Courage or Faith. Two Digimon turn into literal Angels and one of the bad guys is ‘Devilmon’, who was weak to the angel Digimon. Season4 has a fallen angel named Lucifer (well… Lucemon. All Digimon have a -mon on the end) who goes evil as well. Season4 is more random / less elegant with the Christian references as Cherubimom and Seriphmon (angels) don’t really represent Christian ideas anymore IMO.

But Season1 Digimon was the closest you’ll get IMO

But this is really rare. Christianity is treated as an exotic religion / weird Character trait more often than not (much like random Buddhists show up in Hollywood to round out a cast or add a bit of exotic flair).

I dunno. Hellsing Ultimate? Irish Catholic priest is pissed off at a Protestant Vampire who works for the Queen in the 1990s… is referencing ‘The Troubles’ too soon?

Obviously not a Christian story given the huge amounts of hyperviolence. But the Christian references were at least kinda-sorta correct…

That’s not what storage engineers mean when they say “bitrot”.

“Bitrot”, in the scope of ZFS and BTFS means the situation where a hard-drive’s “0” gets randomly flipped to “1” (or vice versa) during storage. It is a well known problem and can happen within “months”. Especially as a 20-TB drive these days is a collection of 160 Trillion bits, there’s a high chance that at least some of those bits malfunction over a period of ~double-digit months.

Each problem has a solution. In this case, Bitrot is “solved” by the above procedure because:

1. Bitrot usually doesn’t happen within single-digit months. So ~6 month regular scrubs nearly guarantees that any bitrot problems you find will be limited in scope, just a few bits at the most.

2. Filesystems like ZFS or BTFS, are designed to handle many many bits of bitrot safely.

3. Scrubbing is a process where you read, and if necessary restore, any files where bitrot has been detected.

Of course, if hard drives are of noticeably worse quality than expected (ex: if you do have a large number of failures in a shorter time frame), or if you’re not using the right filesystem, or if you go too long between your checks (ex: taking 25 months to scrub for bitrot instead of just 6 months), then you might lose data. But we can only plan for the “expected” kinds of bitrot. The kinds that happen within 25 months, or 50 months, or so.

If you’ve gotten screwed by a hard drive (or SSD) that bitrots away in like 5 days or something awful (maybe someone dropped the hard drive and the head scratched a ton of the data away), then there’s nothing you can really do about that.

If you have a NAS, then just put iSCSI disks on the NAS, and network-share those iSCSI fake-disks to your mini-PCs.

iSCSI is “pretend to be a hard-drive over the network”. iSCSI can exist “after” ZFS or BTRFS, meaning your scrubs / scans will fix any issues. So your mini-PC can have a small C: drive, but then be configured so that iSCSI is mostly over the D: iSCSI / Network drive.

iSCSI is very low-level. Windows literally thinks its dealing with a (slow) hard drive over the network. As such, it works even in complex situations like Steam installations, albeit at slower network-speeds (it gotta talk to the NAS before the data comes in) rather than faster direct connection to hard drive (or SSD) speeds.

Bitrot is a solved problem. It is solved by using bitrot-resilient filesystems with regular scans / scrubs. You build everything on top of solved problems, so that you never have to worry about the problem ever again.

Wait, what’s wrong with issuing “ZFS Scan” every 3 to 6 months or so? If it detects bitrot, it immediately fixes it. As long as the bitrot wasn’t too much, most of your data should be fixed. EDIT: I’m a dumb-dumb. The term was “ZFS scrub”, not scan.

If you’re playing with multiple computers, “choosing” one to be a NAS and being extremely careful with its data that its storing makes sense. Regularly scanning all files and attempting repairs (which is just a few clicks with most NAS software) is incredibly easy, and probably could be automated.
