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.

Self hosting is hard. How do you overcome? (lemy.lol)

Not exactly self hosting but maintaining/backing it up is hard for me. So many “what if”s are coming to my mind. Like what if DB gets corrupted? What if the device breaks? If on cloud provider, what if they decide to remove the server?

I need a local server and a remote one that are synced to confidentially self-host things and setting this up is a hassle I don’t want to take.

So my question is how safe is your setup? Are you still enthusiastic with it?

Different phases of power? Did you have 3-phase ran to your house or something?

You could get a Starlink for redundant internet connection. Load balancing / fail over is an interesting challenge if you like to DIY.

In the US at least, most equipment (unless you get into high-and datacenter stuff) runs on 120V. We also use 240V power, but a 240V connection is actually two 120V phases 180-degrees out of sync. The main feed coming into your home is 240V, so your breaker panel splits the circuits evenly between the two phases. Running dual-phase power to a server rack is as simple as just running two 120V circuits from the panel.

My rack only receives a single 120V circuit, but it's backed up by a dual-conversion UPS and a generator on a transfer switch. That was enough for me. For redundancy, though, dual phases, each with its own UPS, and dual-PSU servers are hard ro beat.

Exactly this. 2 phase into house, batteries on each leg. While it would be exceedingly rare for just one phase to go out... i can in theory weather that storm indefinitely.

[–] Saik0Shinigami@lemmy.saik0.com 1 points 5 months ago (1 children)

Nope 240. I have 2x 120v legs.

I actually had verizon home internet (5g lte) to do that... but i need static addresses for some services. I'm still working that out a bit...

Couldn't you use a VPS as the public entry point?

[–] Saik0Shinigami@lemmy.saik0.com 1 points 5 months ago

I could... But it would be a royal pain in the ass to find a VPS that has a clean address to use (especially for email operations).
