Well, if you depend on TM "just working" don't upgrade to 10.11.1 (or to El Cap at all) until you know it's been fixed.
RE not depending on TM, I've had TM fail me (unreadable or otherwise unusable backups) several times over the past many years as have others. I use CCC for automatic nightly backups of my main user directory and periodic whole-system backups. If I really REALLY need something snap-shot saved every hour I rig up a script to do that. TM just hasn't been reliable for me. I fell back from El Cap to Mavericks because of other issues (Mail, odd Screen Sharing behavior, annoyingly-sluggish GUI response, etc.). It still feels like a beta release.
