FYI, you should always have a local copy of any important files and also at least one local backup of them. Never leave the only copy of any important files in the cloud since cloud providers can go out of business, be acquired by another company, the rules & terms of service can change with little notice, and the cloud server may not always be there, plus it can sometimes take lots of time to download items stored in the cloud.
People should always have frequent and regular backups of their computer and all external media (including the cloud) which contains important & unique data. Apple provides Time Machine with macOS to make backups of your computer & external drives very easy & convenient.
