Notes from a small homelab

Things I set up, broke and fixed again: Linux boxes, routers, backups and the occasional script. Written mostly so future me can find them.

• 2026-08-30 Boring, reliable backups with restic and a systemd timer

  Nightly snapshots to an S3-compatible bucket, retention rules, and how I actually test restores.

• 2026-07-12 Splitting a home network into VLANs on OpenWrt

  Guest Wi-Fi, IoT devices and the main LAN on one cheap router with DSA configuration.

• 2026-05-03 pytest fixtures I keep copying between projects

  Temporary directories, fake clocks, and a tiny helper for retrying flaky network calls.
