Let's have an anti cloud rant then. Let's not. Cloud is part of a very sound 3 part strategy, the originating device, NAS or similar, reliable paid for cloud storage. Chances of all 3 failing at the same time are remote. If your house burns down or floods, what's left? If you see interviews with people who have been flooded or forest-fired, they often say... We've lost all the photos, all the.memories. Does anyone have the self-discipline to take a physical device to an off site location each day? Why not make use of all available technology? Very sensitive data can always be saved as an encrypted file.
Oh dear, smoke, house on fire. Backup server will be OK though, it's upstairs.
