Does the Time Machine back up everything?

Time Machine is a built-in backup feature of macOS. It enables you to back up your files and their various versions over time. Once set up, Time Machine can automatically back up a user's data. According to Apple Support, the data it supports for backup includes applications, music, photos, emails, and documents, among others.

If you're new to Mac Time Machine, you might be wondering whether Time Machine is enough to create a proper backup. Does Time Machine back up everything on my Mac? Do I need additional backup software? You'll get the answers in this section.

Time Machine appears to save most personal data. However, it has some limitations. For example, Time Machine does not back up:

    - Your iOS device - Your iCloud content - Your email messages or accounts - Network settings - Some system files and apps

II. How to Set Up and Use Time Machine on a Mac

Now that you know what Time Machine can and cannot back up, the next question is: how do you create a backup with Time Machine on your Mac? Like any built-in backup tool, you have to set it up the first time you use it. To back up your Mac data with Time Machine, you'll need a backup disk. What kind of storage can you use? Let's go over your options.

#1. Prepare the backup drive: What drive can you use?

Many data safety experts recommend that you back up your data to an external hard drive for safety. You have more choices than just an external hard drive, however. If you're a Mac user, your options include an external hard drive, a USB drive, a FireWire drive, a NAS device, a shared Mac, or an AirPort Time Capsule. Most users will want to choose an external hard drive or a USB drive as their backup disk. If you're interested in an external storage device, see Apple's support page for more information.

Here's what to look for in an external drive:

1. Your external hard drive should be large enough to hold all of the data you want to back up.

2. If the disk was formatted previously, make sure the file system is compatible with macOS. Compatible file system formats include APFS, macOS Extended, MS-DOS (FAT), and exFAT.

If the disk is formatted incorrectly, you can format it on the Mac first.

4. There are no brand restrictions for the hard drive you choose; you can pick whichever one you like.

#2. Set up Time Machine on your Mac and enable automatic backups

In this part, connect the backup disk to your Mac and set up Time Machine backups following these instructions.

Step 1: From the Apple menu, choose System Preferences, then click Time Machine.

Step 2. In the Time Machine window that appears, click “Select Backup Disk.” Choose the backup disk that is connected.

Choose a backup disk.

3: Check the box next to "Backup automatically" so that Time Machine will save backups to your backup disk on its own. You can also choose to show Time Machine in the menu bar.

Select the options to automatically back up and show Time Machine in the menu bar.

Step 4: You're done. Time Machine will now begin your first backup.
