Comment on Searching advice for selfhosting critical data

If you really mean life-or-death critical, yeah, 3-2-1 is the starting point.

No data I own is “life-or-death” critical.
I can ask around for contact info again, same with calendar events I had planned. Some documents can be restored via the original service or by paying a fee to get a new original document, I still have folders full of originals in paper form. Some info can be restored by looking through my bank account or online buying activity. Losing my photos would be really sad, but nothing of that will kill me or destroy my life.
But I definitely can save the most critical stuff (probably a few GB only), if nextcloud (or some alternative) has the ability to regularly export these to an on-disk location. This way, some backup utility like restic or rsnapshot shoud be able to do the job.

Okay so not critical, just mildly inconvenient if lost.
I would just keep one copy in RAID, and for the most important stuff a second copy locally or in the cloud. Yes, RAID is not backup, but a disk failure is probably the most likely failure scenario. Corruption is the second most likely.

I wouldn’t put it at “mildly inconvenient”, as the photos I could lose can never be restored. Most of the other things can. I’d be really sad if I lost all the photos, but it wouldn’t threaten my existence in any way.
I’m sorry, I should have specified in more detail what I meant by “critical”.
It’s not life-threatening, it’s just critical to me. It’s kinda like “my priciest possession” could mean a yacht or a half-dead car, depending on the context.
