I was helping someone 12 months ago with their Mac OS backup. I installed an entry-level 2-bay Synology for them in their wiring closet. 12 Months Later I was there again today for a different problem and curiosity got the better of me. I asked them "how is the Synology..." "what..?" they replied" "The backup device...I said "is that connected still?" they said. "I hope so" I said Using Finder, I eagerly accessed the device and to my complete amazement it had completed a backup just 10 minutes previously. There were around 40 different snapshots that user could have rolled backed to. And the user did not even know there it was there! No scary error messages. No "back-up failed" error messages. I can finally see what the hype about Synology is about. Flawless.
