Even if you’re using Backblaze, our software can’t back up what’s not there. Here’s a big problem: You’re trusting Apple with those files alone, which is counter to the triple backup best practice. Sierra can also automatically clear space off of your hard drive by “purging” old files and uploading them to iCloud Drive. Apple’s most recent Mac operating system update, Sierra, also allows you to upload the contents of your desktop and Documents folders to the cloud. It lets you sync files and folders between devices. ICloud Drive is Apple’s alternative to Dropbox. You can also back up your iOS devices to iCloud. You can even use iCloud to locate missing devices. iCloud Family Sharing lets you share iTunes music, movies, apps, and iBooks purchases with other family members. ICloud also serves as a repository for photos and videos and lets you store files. Having all your files synced among your devices is convenient, but it’s not the same as a backup. You’re always up to date regardless of whether you’re working on the Mac, iPhone, or iPad, or even just signing in on the web. ICloud syncs calendars, contacts, mail, Safari bookmarks, notes, and more. Let me save you that fate by exploring what iCloud is and is not. Some of us only find out too late that it isn’t, and lose precious information as a result.


Many of us with iCloud accounts just assume all our data is backed up. I use it and so do some of my colleagues at Backblaze. Let me say at the outset that this isn’t a warning against using iCloud. Now more than ever, Apple is blurring the line between sync and backup, but don’t mistake iCloud for a true backup solution like Backblaze. Apple’s iCloud gives Mac and iPhone users an easy way to sync data between devices.
