| 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. Unlock the repo using git-crypt unlock /path/to/git-crypt/key.
3. Create a new host configuration in the host-configurations folder.
4. Source the host configuration from hardware-configuration.nix.
5. 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 to backup everything on my server, and all of my important documents are stored in Syncthing, which is backed up from my server.
