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.

Hello!! Some recent technical problems on my family's NAS gave me a big scare and finally pushed me to figure out a way to back it all up. I'm asking here specifically because I really don't know where to even starts because of the fact I've got just under 50 terabytes worth of data stored in a 7-disk RAID-5 and would prefer to keep it cheap. What are your suggestions?

How much of that 50 terabytes is media downloaded from the Internet? Because the cheapest way would be to trust that it's already backed up on the Internet and then use one of the usual services like B2 by Backblaze or Storagebox by Hetzner to back the rest of it up.

But... can we trust that we will have stuff available on the internet in the future?

You can replicate across more than one provider and do automated regular monitoring that backups are still accessible.

If one goes down you hopefully have time to figure out a replacment before the other(s) do.

Probably not worth it for a bunch of xvid dvdrips or historical archives of full system-level backups but for critical data it's sensible.
