I put together a practical two-hour home lab maintenance task list focused on the things I tend to neglect when everything appears to be working: checking updates, verifying backups, cleaning storage, patching, rebooting long-running server. And, also, validating critical services, and documenting what changed.

The main idea is that it doesn't take a lot of time to get rid of a lot of uncertainty in the lab without it being an all-day exercise. Curious what other people put at the top of their home lab maintenance checklist?
