Comment on It will be great, they said...
ysjet@lemmy.world 1 week agoI mean, my use case is abnormal and generally has more beef behind it than most people would have, yes, but a simpler, cheaper version of what I have set up is kind of a no-brainer if you want to self-host.
e.g. I don’t think a simple cyberpower/APC ups on your home server is any kind of a weird ‘specialty’ thing, and it should definitely run your server for 2-3 hours during an outage for like $100-150 if you grab it on sale (which, you know, why wouldn’t you?) As for the generator, I don’t have that for my network stack, I have that for my fridge/deep freeze lol. It can just also recharge my UPS if it’s really that big of a deal.
As for cell backup, that’s definitely less a ‘common’ homeserver thing, but I’m only paying like $14/mo for my cell backup connection from tello for 5gb of 5G. Hardly breaking the bank, and honestly probably overkill, you could likely get away with their $10/mo 2gb plan. No complaints with it either, I use them for my regular cell plan too. if you were interesting in self-hosting your own email server and wanted better uptime than 99.9%, you probably don’t even need that if your ISP only sucks slightly instead of mostly, but it allows you to just not care about your ISP having extended downtime.

If you have a regular data plan that you use if your internet goes down, you’re server would technically have an internet connection, but your services (like email) still wouldn’t work would it?
Do you have some type of setup that keeps that working on data?
I don’t know how buying the ISPs data addon works, but I’ve been skeptical that that swap over would keep anything online either (but getting a generic data plan surely cant work at all right?).

So this sort of a setup is called Dual-WAN, and yes, it allows it all to work. Basically, my router has two connections to the internet- a cable modem on one port, which connects to Spectrum, and a cell modem on another port, which has my sim card on it. Both provide internet access simultaneously. My router is then configured to reach the internet via what it decides is the ‘best’ internet. In my case, because my cell connection is metered, I have it configured so that it prefers the spectrum connection, and only falls back to the cell connection if the spectrum connection is losing traffic, and only for as long as that connection is losing traffic. Note that a dedicated cell modem is not necessarily required- some routers have sim card slots themselves, for exactly this reason, and tend to make this sort of configuration very simple to do. I’m personally using a small computer running OPNSense, which is again, probably overkill for the average homelabber, but you don’t need something that complicated.
As a result, my server always has access to the internet, and should you configure your firewalls appropriately, the internet will then always have access to your server. There’s some details here and there about IP address caching, dns resolution, and the like which have various solutions from DDNS to an external proxy/loadbalancer/etc, but those are more implementation details.

Oh okay, so it doesn’t work then is what I’m gathering (for email).

That is, in fact, exactly the opposite of what I just said.
