I just purchased a new Macbook Air and was wondering how I can back up all files and such on the cloud before I trade in my old Macbook Pro. Is there a way to back it up and show that all files are saved?
MacBook Pro 13″, macOS 10.13
Apple offers iCloud Backup for iPhones and iPads but not for Mac computers.
It is possible to sync data from a Mac to iCloud if you turn on those options (e.g., iCloud Photos, iCloud Drive including the Desktop & Documents option). Syncing has some of the benefits of a backup (and the benefit of being offsite) but is not the same as a backup. Major differences include the fact that not everything on your Mac can be synced and the fact that if you delete something, accidentally or otherwise, there is only a limited time period (30 days in most cases) during which it can be recovered.
