There is plenty of backup management software

Could you provide any examples to start looking into?

1. You clearly didn’t read my post
2. You’re rude
3. You start every single comment with the slightest mention of syncthing with the same lines regardless of context

With sync you only have replicants of one file that can be lost through the sync.

You seem to be missing/ignoring that sync will protect against data loss from lost/broken devices. When that happens, those connections are severed with no deletions propagating through them. Not only that, you can configure syncthing to retain older versions for over a year to avoid issues of unwanted edits.

Or mini pc with one drive.

You have to be joking with this. There is no way I’m letting that tracker-filled ransomware near any of my computers.

having local redundancy (e.g. Mirroring) isn’t really necessary.

Simple mirroring doesn’t protect against bitrot. RAID 6 does.

You’re clearly not suited for giving out advice, so you’re getting ignored and blocked. Don’t let the door hit you on the way out.

Try looking up videos from an old PBS show called “This Old House”. There should be lots of videos up on Youtube. The hosts are professional contractors and each season they rennovate an old house and use it as a way to teach the viewers how to do proper repairs. They also have tutorials on plumbing, wiring, etc.

You can also try getting an Arduino or Raspberry Pi and start trying to use them for random tinkering projects. There’s plenty of examples and walkthroughs on Adafruit’s websites for examples. That being said, you might need to look up guides on some different skills like soldering, but that’s thr benefit - the projects get you to learn new skills.

Sorry if this doesn’t directly address your request to learn resourcefulness, but there’s a point to it. In my opinion, gaining a broader skillset via DIY projects helps with being resourceful, as you’re equipped with more tools to apply to a given problem.

Friendica is mostly developed in France iirc
