Backing up your Mac is simple and important. We recommend it for everyone.
Back up with Time Machine
Time Machine is the built-in backup feature of your Mac. It’s a complete backup solution, but you can use other backup methods as well.

Tip: You can use a shared Mac that’s on the same network as your MacBook Air as a backup destination.On the other Mac, go to the Sharing pane of System Preferences, then turn on File Sharing.Add a shared folder, secondary click (that is, right-click) the folder, choose Advanced Options, then click “Share as Time Machine backup destination.”. In a nutshell, the system backup makes an entire clone of Mac’s storage on a secure device. Mostly, Time Machine is used to take the local backup of Mac. Since it is already a part of Mac, no additional tool is needed to perform the system backup. Instead we wanted to create a product that felt integrated well with the Mac. So we built Backblaze's cloud backup for Mac using Apple's Xcode and put the controls in the System Preferences using a native interface. It doesn't matter if you are running macOS 10.8 or higher, Backblaze's online backup. Time Machine is a very good inbuilt backup software for MAC that can be used to.
You can also use iCloud and iCloud Drive to store files, such as your photos, documents, and music.

To see the size of a specific file or folder, click it once and then press Command-I. To see storage information about your Mac, click the Apple menu in the top-left of your screen. Choose About This Mac and click the Storage tab. For Time Machine backups, it's good to use a drive that has at least twice the storage capacity of your Mac.
