I completely understand this POV. My reasoning is that while I have physical hardware backups, they too could fail and without warning or reason. Why not have another method as another failsafe that doesn’t rely on a physical device? $70 a year for unlimited data backup isn’t a bad deal as an additional back up method. Plus it automatically scans for file changes and new ones to back up. I like the safe method, but I’m constantly adding more media so I would have to update those drives too occasionally.There is nothing like PHYSICAL ownership of your data and your backups.
Get a home safe, fire and water proof. Make backups to a drive, brick, with a simple USB interface in a standard format (NTFS). Keep the drive in the safe.
