Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
Rules:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.
-
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
-
No trolling.
-
No low-effort posts. This is subjective and will largely be determined by the community member reports.

I enjoyed the depth of this answer. That being said...
4 copies seems like a level of paranoia that is not practical for the average consumer.
3 is what I use, and I consider that an already more advanced use case.
2 is probably most practical for the average person.
Why do I say this? The cost of the backup solution needs to be less than the value of the data itself x the effort to recover the incrementally missing data x the value of your time x the chance of failure.
In my experience, very few people have data that is so valuable that they need such a very thorough backup solution. Honestly, a 2$ thumb drive can contain most of the data the average user would actually miss and can't easily find again scouring online.
Absolutely correct. I used to maintain vigorous whole disk backups, and made sure my MacBook also had regular Time Machine backups and that kind of thing.
Then I realized there are actually tiers of important data. The most important stuff would be on the order of megabytes (tax documents, my lease, historical records of that stuff, and config files that I’ve built up over time).
Then I have my vacation photos and videos. Family photos. A few gigabytes. That’s not that much in the grand scheme and it’s still easy to back these up to a cloud service for minimal to no cost.
The rest of the data on my computer is easily recoverable or can be reconstructed with minimal effort. The OS install. The games. Media from online. I would not bother backing up this stuff.
Once this stuff is in perspective it’s very easy to devise a backup solution that fits your needs at an appropriate price. Not everyone has usage like mine and maybe their important data is much larger than mine is, but the point is we should think about which of the data is actually important, and not blindly duplicate pointless data.
