I host everything on a single server. This is generally advised against, because if it goes down then you lose access to all services, but it hasn’t been a problem for me yet.
I use Unraid, with one parity drive. This provides me with comfort against single drives failures.
I then have backup scripts which backup any data I think is important to an external HDD connected to the server. This provides me with extra comfort against single drive failures, and the comfort that if the server went down, I can relatively easily plug the external into another machine and restore some essential services.
I also then have automatic backups of those backups to a cloud provider. This provides me with the comfort that if anything is stolen, damaged, lost in a fire, etc, I still have all my most important data available.










Question… I often see rack mounted servers with those small Ethernet patch cables running between two adjacent devices, like you have there. I’ve always assumed one of the devices is a switch, but it’s never made sense to me why there’s so many connections between those two.
What are those devices, and why so many connections between them? Like, as far as I can tell, in one instance you have a cable running from the top device to a small switch resting on top, which then runs from the switch to the lower device… Despite all of the other Ethernet running directly from the top to the bottom. What is going on here??
