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:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. 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.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

  7. No low-effort posts. This is subjective and will largely be determined by the community member reports.

I have a 56 TB local Unraid NAS that is parity protected against single drive failure, and while I think a single drive failing and being parity recovered covers data loss 95% of the time, I'm always concerned about two drives failing or a site-/system-wide disaster that takes out the whole NAS.

For other larger local hosters who are smarter and more prepared, what do you do? Do you sync it off site? How do you deal with cost and bandwidth needs if so? What other backup strategies do you use?

(Sorry if this standard scenario has been discussed - searching didn't turn up anything.)

You'll think I'm crazy, and you're not wrong, but: sneakernet.

Every time I run the numbers on cloud providers, I'm stuck with one conclusion: shit's expensive. Way more expensive than the cost of a few hard drives when calculated over the life expectancy of those drives.

So I use hard drives. I periodically copy everything to external, encrypted drives. Then I put those drives in a safe place off-site.

On top of that, I run much leaner and more frequent backups of more dynamic and important data. I offload those smaller backups to cloud services. Over the years I've picked up a number of lifetime cloud storage subscriptions from not-too-shady companies, mostly from Black Friday sales. I've already gotten my money's worth out of most of them and it doesn't look like they're going to fold anytime soon. There are a lot of shady companies out there so you should be skeptical when you see "lifetime" sales, but every now and then a legit deal pops up.

I will also confess that a lot of my data is not truly backed up at all. If it's something I could realistically recreate or redownload, I don't bother spending much of my own time and money backing it up unless it's, like, really really important to me. Yes, it will be a pain in the ass when shit eventually hits the fan. It's a calculated risk.

I am watching this thread with great interest, hoping to be swayed into something more modern and robust.

Sneakernet crew here too. My work offsite backup is in my backpack. Few times per week I do a sync which takes a few minutes and take it home again. (The sync archives old versions of files and the drive is encrypted.)

We tried several cloud-based solutions and they were all rather expensive or just plain hard to run to completion or both.
