I have 3 servers:

  • my house
  • my sister house
  • my parents house

My server has a lot of services (Nextcloud and Immich the ones that use more space), the other 2 servers only have Home Assistant, Frigate and some shared folders. On my server I use Backrest to backup locally and on Wasabi, the other 2…well…are not backed up 🙈 …yet!

I was thinking to buy a couple of 14/20TB drives and install them in my parents and sister servers so that each server can backup data on the other 2. The backup will be done locally on all the servers with Backrest. How do I copy the backups across servers? Should I use Syncthing or is it better to use one repository per location on each Backrest? Or…other ideas?

Thanks!

    Tailscale+Headscale or Zerotier, use whatever backup software you want for the local backups. Simple script to rsync backups to other sites and remove copies past a certain age.

    Pretty simple, and no need to expose machines in any less than safe ways.

        Tailscale is both a client and server. If you use only Tailscale, you have to pay for the service after so many devices are connected, which by all means support the company and do so and avoid using Headscale.

        Headscale is an open source implementation of the Tailscale service, so it’s free to use with all the usual Tailscale clients published. You setup Headscale somewhere, register your Tailscale clients to it, and use it like usual. It’s just skipping the need to pay for Tailscale servers as a service, and gives you greater control over how traffic routed. Completely optional.

          Yeah but it’s like 100 devices, I think. And I believe 3 users (meaning under one account; sharing a device with someone who makes their own account doesn’t count as a “user”). You’re right, but they’re pretty generous.

          I don’t think it takes many resources to provide the service to consumers; it’s not like you’re using any of their bandwidth (minus the tiny amount used for coordination between clients). Oh, or if you use their DERP servers (encrypted, but still).

          In general, people should know there are self hosted, truly private options, though. So thanks for mentioning Headscale.
