The Apple Time machine is a built-in backup feature on your Mac. It regularly takes snapshots of your entire system and saves them on an external drive.
Apple launched Time Machine with Mac OS X 10.5 Leopard, and it is still there on the latest macOS versions. You can also encrypt a Time Machine backup with a password so you can restore it.
How Does ‘Time Machine’ On Mac Work?
You can attach an external hard disk, AirPort Time Capsule, or use another Mac to take a Time Machine backup.
AirPort Time Capsule is an external wireless backup solution that Apple launched in 2008 and discontinued in 2018.
You can use Time Machine to restore specific files or the entire system. It backs up apps, music, photos, email, and other documents from your Mac, so you won’t miss out on anything.
It takes hourly, daily, and even monthly backups of everything in your system. Time Machine optimizes this process by only backing up files that have changed since the last backup.
Time Machine automatically deletes the oldest backups when your external storage peaks and makes room for the new ones.
Here are a couple of things you should know before making a Time Machine backup.
- Since it takes regular full-system backups, use at least a 1TB disk external drive.
- The drive you use will be formatted to APFS.
- You can use an external AirPort Time Capsule for wireless backups.
