I agree with the author. I use Time Machine but don&#x27;t rely on it.<p>I also had a disk with errors that OSX could not fix. I ended up having to reformat the drive using a Linux laptop. I have had two USB external drives totally die in ten years so I rotate between three drives.<p>I have cheap cloud storage via OneDrive so I sometimes create dated encrypted ZIP files and push them to OneDrive - additional backup safety. I do the same with Google Drive.
