But I don't think the user was using it as a backup, it was using it as a storage product. As in, I'm working on a file across multiple devices, so I'm going to store it in iCloud Drive so everything is kept up to date.
I do understand that, hence why I was highlighting that if anyone were to think this tool will cover you for data loss, it wont.
Personally, any product that allows accidental deletion in one place that gets synchronised across all devices is a bad, bad thing. It only takes one virus or rogue app to delete the contents of a directory and the iCloud software will do it's thing and spread it.
Theoretically.
