What are your Homelab goals for 2025? (slrpnk.net)

Personally will be trying to transform my server which is currently in a fractal R5 case, into a small-ish Homelab rack, combined with all my network equipment. Will require complete relocation of all network equipment in the house as well as cables so it will be a bit of a project. Also on the lookout for a good quality rack so let me know if you have any recs. Still unsure if u want to do full width rack or mini. Part of me really want the UDM Pro from Unifi..

What are your goals and thing you want to accomplish during 2025?

I want to move my whole server to NixOS. It's gotten to the point where I have no idea where all the Ubuntu config files went, and handling half of it via Docker vs baremetal. I hope this will allow me to set up proper backups as well, and maybe get better at Nix! I started a few days ago using the VM feature, but it's tricky to work on for now, perhaps I haven't found the right workflow.

I went this route from the start and love it. In case you need some resources:

VimJoyer is excellent: https://www.youtube.com/watch?v=a67Sv4Mbxmc
Do secrets using SOPS: https://www.youtube.com/watch?v=G5f6GC7SnhU
NixOS and Restic are an amazing combination, full backups in 20 lines of config. This article was my best find for this: https://francis.begyn.be/blog/nixos-restic-backups . Tip: you can easily write systemd services to trigger each software's preferred backup strategy and simply schedule them to run before the Restic backup - I have them all copy the backups to one folder that then Restic backs up, works great for me!

Hope this helps a bit. I found the effort to be very worth it, but took me almost half a year to get comfortable with it.

Another vote for restic, best backup software I've ever used.

Thank you! It definitely does, I will be using that Restic article for sure! I actually use NixOS on my main laptop, which I found via Vimjoyer's videos. It's great, though I wish documentation for more advanced usage was more readily available. I started making the server, currently my biggest roadblock is testing the infrastructure without going live (I made the flake generate a VM for now but it takes a long time to build it every edit and I can't even get ssh working) and figuring out how I'll eventually install it with minimal downtime.

On the topic of build times, it took me too long to learn that nixos-rebuild supports remote build workers and targets.

For example, if I am editing on my laptop, want to build on my desktop, and apply the build to my file server, then I'd run...

me@laptop$ nixos-rebuild test \
--flake ~/wherever-it-lives \
--build-host desktop \
--target-host file-server \
--use-remote-sudo

The host names should match the name of the nixosConfiguration output from your flake. If they don't I think you can specify like, --target-host .#some-machine

Remote sudo avoids having to SSH as root.

Bonus tip: Having Tailscale on every machine makes this work reliably from anywhere, network speed as the limit.
