I like weekend maintenance because it is quiet and easy to schedule. The goal is not to inspect everything, only to catch the obvious problems early.
Checks worth keeping
- Confirm recent backups exist and can be listed.
- Check storage usage before it becomes urgent.
- Review expiring certificates and renewal dates.
- Look for repeated errors in important logs.
A short routine is more likely to survive than a perfect one. Consistency matters more than detail for this kind of work.
