Without a proper backup system in place, though, you could lose all of those digital files in a blink of an eye. But don't worry; backing up your Mac is so surprisingly simple, you only have to set it up once to enjoy the peace of mind that all your files are safe. Here's how to back up your computer in macOS using Time Machine and other utilities. Back up your computer to Backup Plus Desktop What is a backup? There are two types of backup: System backup: A system backup copies everything on your computer onto an external storage device including the operating system, applications and data.If the computer’s hard drive fails, the computer can be restored to its former state with the backed up system data.

Regular backups are essential. When your hard drive dies—and it will die eventually—it’s important to know you’ve got another copy of everything somewhere. PC users can use Windows’ File History to back up their data, but Mac users have something that’s arguably simpler and more powerful: Time Machine.
This free backup tool, included with every Mac, keeps a day’s worth of hourly backups, a month’s worth of daily backups, and weekly backups until there’s no more space. MacBooks will also create “local snapshots” on their internal storage, so you’ve got a small record to work with even when you’re not plugged in.
How to Back Up With Time Machine

The easiest way to use Time Machine is to connect an external drive to your Mac. You’ll be asked if you want to configure it as a Time Machine drive; click “Use as Backup Disk” if that’s what you want to do. Click the “Encrypt Backup Disk” option if you want to secure your backup disks with encryption.

You can optionally click “Show Time Machine in menu bar” if you’d like to track backups from there.
While external hard drives are the simplest option, it’s also possible to back up wirelessly over the network. The simplest tool for this is Apple’s Airport Time Capsule, a combination router and storage device that makes backing up easy. Sadly, Apple doesn’t seem committed to updating this device anytime soon, but you can use another Mac as a Time Machine server instead, or even a Raspberry Pi if you’re feeling creative.
You can even have your Mac back up to multiple locations, rotating between them so you can have backups in two or more locations.
Enabling Time Machine on a MacBook will also enable the “local snapshots” feature. Your Mac will save a single daily snapshot as well as a single weekly snapshot of your files to its internal storage if the Time Machine backup drive isn’t available. This provides you with a way to recover deleted files or restore previous versions of files even if you’re away from your backup drive for a while.

While Time Machine does include everything by default, you can click the Options button in the Time Machine window and exclude certain folders. For example, you could exclude your /Applications folder to save space on the Time Machine backup.
Automatic vs. Manual Backups
The first Time Machine backup will take the longest, as everything on your drive is backed up. Future backups won’t take as long, as only new and changed files will have to be backed up.
Time Machine normally functions automatically. If your drive is connected to the computer or the network location is available, it will back up once per hour. You could disconnect your external drive when using your MacBook during the day and plug it in when you get home in the evening. Your Mac would back up when the drive is connected.
You can also choose to perform manual backups instead. To do this, open Time Machine’s settings screen and toggle Time Machine to “Off.” You can then click the Time Machine icon on the menu bar and select “Back Up Now” to perform a manual backup at any time. Automatic backups are usually a better option — you’ll have more backups and you won’t be able to forget about it.
How to Restore Individual Files from a Backup
Click the Time Machine icon on the menu bar and select “Enter Time Machine” to enter the restore interface. This screen allows you to locate deleted files or previous versions of files and restore them.
Select a date and time at the bottom-right corner of the window to “go back in time” to the point where the file you want to restore existed. Dates in pink indicate the backup is stored on an external drive, while dates in white indicate local snapshots stored on your Mac’s internal storage.
Locate a file you want to restore, select it, and click the “Restore” button to restore it to the same folder on your Mac. If it would overwrite and existing file, you’ll be asked what you want to do.
You can also select a file and press the spacebar to preview it with Quick Look before restoring it.
Time Machine includes a search feature as well. Just type a search into the search box in the Finder window inside Time Machine to search for a file you want to restore.

Time Machine also allows you to restore an entire Mac’s system state. You can only do this if the backup was created on the same model of Mac. To do this, hold down Command+R as your Mac boots to access Recovery mode. You’ll see an option to restore your entire system from a a Time Machine Backup here.
Time Machine also backs up your macOS Recovery files to your Time Machine backup disk, so you can hold the “Option” key as you boot, select the Time Machine drive, and boot straight to recovery mode even if the recovery system is unavailable on your Mac.
How to Restore Time Machine Backups on Another Mac

How to Restore a Time Machine Backup on Windows
Time Machine requires a drive formatted with the Mac HFS+ file system, so if you want to restore your Time Machine files using Windows, you need you’ll need to install an application like the free HFSExplorer that can read a HFS+ file system and copy files from it. HFSExplorer unfortunately requires Java, but it’s the only free application we know of that allows you to read HFS+ file systems on Windows.
