Reliability in this lab is less about pretending everything is production-grade and more about knowing what actually matters when something breaks.
The reliability-sensitive services are DNS filtering, remote access, Home Assistant, the NAS, Proxmox backups, and the access paths used to reach everything else.
Current Signals
- Proxmox Backup Server protects VMs and LXC containers.
- Synology snapshots cover some shared folders.
- Cloudflare sends downtime emails for the tunnel.
- Uptime Kuma exists for service checks, though it is useful rather than mission-critical.
- Updates are reviewed deliberately, sometimes with AI help to check release notes and vulnerability relevance before applying changes.
- Semaphore and Ansible experiments are being used as a path toward more repeatable host and service maintenance.
Operational Habits
Core services are updated carefully instead of immediately. VM snapshots are used before changes where possible. Docker services are reviewed periodically, with Git-backed Compose stacks providing a trail for what changed. The current update workflow is intentionally semi-manual: check what changed, decide whether the update matters, then apply it with a rollback path in mind.
The next useful improvement is a small restore-test and runbook routine: prove a VM restore, prove a file restore, document what to do when DNS is down, and document how to reach the lab if the main compute host is offline.
