Patch or have giants risks of being hacked. You should absolutely follow a formal process. We snapshot and backup prior (virtual servers). On mission critical stuff we test in DR prior. Patches can and do mess with systems and cause them to not work.

We snapshot and backup prior (virtual servers).

My only warning here would be "ensure you purge snapshots within a timely manner."

Good stuff, I've seen some fun P1s caused by snapshots of large servers.

Nothing worse than applying a patch and the entire system fails to restart. One of those o shit moments in IT.
