have 2 flash/hard/whatever drives: A and B

once a month (or at what ever frequency you can sustain)

backup your data to A and next cycle backup your data to B

nothing fancy or technical, just some basic consistent backups.

if you can do that you’ll likely be fine. There are nearly infinitely many enhancements you can do if you are more technical or can follow technical instructions.

That is just the gateway drug to bootstrapping.

I refuse to use a terminal emulator that needs more than 100MB of RAM to display 80x24 green text on a black display

checksums at the filesystem level does nothing to protect against memory corruption which can overwrite everything on your disk with null values and a matching checksum; fail to write anything to disk and/or do nothing.

But that is the gamble you take every day with every GB of RAM you have.

the correct answer is Gemini or gopher.

No ECC, absolutely worthless for a NAS if you care about your data.

a git mirror of the content is the golden standard if you can do that.

It is recommended by the permacomputing community

Raid stopped being optimal now that btrfs and ZFS exist.

If you plan on doing matching drives ZFS is recommended

If you expect mismatched disks, btrfs will work.

If you are most worried about stability get a computer with ECC memory.

If you are most worried about performance, use SSD drives.

If you want a bunch of storage for cheap, use spinning disks (unless you exceed the 100TB capacity range)

looks interesting but does it have download/clone/mirror setup so that it doesn’t become another data graveyard?

Support the FSF if that is a legitimate concern to you

The missing bit is social action, which no amount of software can solve.

So effectively light enough that it could run on a raspberry PI 4. Well that would put you under 10W

Well the first question is what software you NEED to run, then we can figure out hardware.

Your ZFS backup strategy should be to follow one of the following rulesets:

3-2-1 [3 copies of the data at 2 different locations for the 1 purpose of preserving the data]

4-3-2-1 [4 copies of the data at 3 different locations in 2 different types of media for the 1 purpose of preserving the data]

5-4-3-2-1 [5 copies of the data at 4 different locations across 3 different continents in 2 different types of media for the 1 purpose of preserving the data]

The details of the backup is more if you have a second system to enable ZFS send/receive or if you have to transport deltas from ZFS send

indeed, the default open and cooperation requires what social scientists call a cultural subsidy which historically is contributed by zealots.

if you look at the Open Source Software community, you’ll notice the FSF pulls the standard towards stability and publicly shames those who try to shift the standard towards proprietary.

but if you look at the Open Hardware community, you’ll notice that it is lacking a sizable FSF community and it is sliding back into proprietary silos (Aka it is slowly dying in terms of actual openness).

heating is not done year around (365.25 days/year) for the majority of the world’s population.

Hence why places which need heating year around are generally considered an edge case.
