Free, practical write-ups from the same procedures the products are built from. A reader who never buys anything should still leave with their answer.
Free chapter. Chapter 1 of The Homelab Ops Handbook in full: the one inventory that backups, disaster recovery, monitoring and patching all read from. Hardware, VMs, services, network segments, a credential pointer map and a dependency chain, plus onboarding and decommission checklists.
A backup job that reports success is not a backup. Here's the drill: verify jobs in Proxmox Backup Server, restore to a scratch VMID, boot it, check the data, and audit retention, without touching production.
The job liveness rule: a job is green only when its last success is inside a budget you chose on purpose. Stamp files written on success only, four places to get a timestamp, a threshold table, and why the check belongs on a different host than the job.
No alert without an action, and a written reason beside every threshold. Sixteen rules with the reasoning for each number, the four de-noising moves in order, severity routing, inhibition, and the quarterly fifteen-minute review that keeps the list short.
One monthly window, a cadence and rollback method per layer, the six steps of the window itself, a rollback decision table, and the same-day fast path for an actively-exploited CVE.
