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.

Server for a boat (lemmy.world)

Good day, friends. Since catching the self-hosting bug, I've set up a couple of Proxmox home servers with a bunch of services I enjoy.

Now I'd like to set up a server and local network on my sailboat so I can self-host servarr, pihole, and other services while traveling. The tricky part is that everything on the boat is 12V and I would rather not use an inverter, if possible. Also, it needs to be ultra-low power so I can leave it on at all times and not to deplete my batteries too much.

Criteria:

  • ultra-low power
  • Small form factor
  • runs on 12V
  • 10 TB of storage plus ability to make full local backup
  • Capable of hosting servarr, audiobookshelf, freshrss, etc. via docker
  • HDMI output
  • Full local mirror/backup of the entire file system, including the media library.
  • We will have two laptops and two Android phones to access the server, so the server doesn't need to run a desktop environment.

I'll have a mobile wifi router and a cellular signal booster (or maybe Starlink eventually) for internet access. Since internet bandwidth will be limited and expensive while traveling, I don't want to have to re-download a massive media llibrary if the storage media fail. Thus, I want the media library to be mirrored or fully backed up or synced locally.

What hardware and Linux distro would you use in this situation?

For hardware I recommend this guy to everyone: CWWK N100 mini PC w/ 4xNVMe hat

Get 4x4TB NVMe drives and you'll have 12TB usable storage + parity drive.

It also uses a 12V power supply.

Relying on 4 nvme drive for low power isn't ideal as nvme drive needs about twice more power compare to sata SSD.

That's not correct. They can draw significantly more power when in use but also consume significantly less when not in use. You can use 2x SATA with this but you're gonna spend more $$$/TB
