## Installation Instructions

```

| WARNING:                                                                   |
|                                                                            |
| Don't install somebody else's NixOS configs. Use them as inspiration, but  |
| don't actually just blindly copy.                                          |
'----------------------------------------------------------------------------'
```

To install this configuration,

1. Clone this repository to `/etc/nixos` on a NixOS system.
2. Create a new host configuration in the `host-configurations` folder.
3. Source the host configuration from `hardware-configuration.nix`.
4. Run `sudo nixos-rebuild switch --upgrade`.

## Goals

* Infrastructure as code
* Immutable infrastructure (as much as possible)
* Everything backed up to B2
* Everything backed up to onsite location

### Uptime

* Can blow away all servers (but not data) and restore in under an hour
* Can restore all data within one day after catastrophic failure (everything
  goes down, including data)

  * From local backup: 1 day
  * From B2: 2 days

## Backup Strategy

I am using [Restic](https://github.com/restic/restic) to backup everything on my
server, and all of my important documents are stored in Syncthing, which is
backed up from my server.
