Infrastructure decisions rarely announce themselves. A team notices a slow page, then a failed job, then a weekend spent restoring something that should never have been lost. The work below is the boring kind that prevents those weekends.
Start with what you can measure. Disk headroom, memory pressure and the age of your last verified restore tell you more than any dashboard average. A restore that has never been tested is not a backup; it is a hope.
For a deeper walkthrough see this backup strategy write-up, which covers the same ground with worked examples.
None of this is exotic. It is simply the difference between a system that degrades predictably and one that fails all at once.
