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.
Replacing the Internal Backup Battery Your Mac Pro uses a CR 2032 Lithium battery that preserves settings, such as the date and time, when your Mac Pro is off. If you notice intermittent problems when your Mac Pro starts up or changes in the date and time settings, you may need to replace the battery.

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.

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.
To check the progress of your backups head to System Preferences > Time Machine.
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.
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.
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.
To restore files from a Time Machine backup on another Mac, navigate to the /Applications/Utilities folder and open the Migration Assistant application. You can also press Command+Space, search for Migration Assistant, and press Enter.
Connect the Time Machine backup drive and use Migration Assistant to migrate the backed up files from your previous Mac to your new Mac.
Migration Assistant is also offered when setting up a new Mac, making a Time Machine backup a very quick way to get all your files and applications onto a new computer.
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.

If you’d just like to stop using Time Machine and use the drive with a Windows PC, you can reformat the drive with the NTFS or FAT32 file systems using the Windows Disk Management tool.
Time Machine isn’t a cross-platform backup solution, but it is very powerful. If you’re a Mac user, you should be using it.
READ NEXTWe all know how important it is to back up our Mac on a regular basis. While macOS is more stable than ever and Mac's hardly ever crash, it only needs one piece of software behaving badly to wipe out lots of precious data. And even if the worst never happens, many of us trash files only to discover later that we need them again. A backup of your Mac makes it easy to retrieve that file.
There are several different ways to back up a Mac, and for absolute safety, you should use all of them.
This type of backup makes a copy of all your data the first time you run it then, at regular intervals, scans your Mac, identifies files that have been added or changed, and copies those to a backup file. This means that each run of the backup is quick and uses few resources, because it's only backing up new or changed files.
There are a some things to remember when creating a backup strategy:
The other prevalent type of backup is a complete clone of your startup drive, usually a bootable version. This gives you a complete copy of your main drive and allows you to get back up and running again quickly should a disaster strike. It's useful when you install a beta version of a new macOS or when you're doing anything on your Mac that might cause a problem for the OS. Depending on the tool you use to create the clone — Disk Utility, Get Backup Pro, and Disk Drill being the most popular ones — you can reconnect it to your Mac and update on a regular basis, making new copies only of files that have been added or changed. That means your clone is always up to date.
Disk Utility is a default tool that comes pre-installed on your Mac. To use it to clone your drive, follow these simple steps:
Note: The backup copy created using Disk Utility is not bootable.
Get Backup Pro can serve as a great companion to Time Machine for its extra features like creating bootable backups using disk cloning functionality. So you can copy one entire drive to another drive, and boot from the copy in an emergency. You can simply boot from the cloned drive and be up and running again in minutes. And one more feature: you can update your cloned volume.
Try Get Backup Pro for free to clone your disk volume to get a backup disk that can be booted up at any moment, whether you have new APFS or traditional HFS+.
Disk Drill is one of the most popular apps for protecting, recovering and backing up your data. Although intuitive and easy to use, there are some tricks to help you get the most out of it.
When Disk Drill warns you that the external hard drive does not have enough space, either free up space on the external drive by deleting files or find another hard drive with more space. If there is sufficient space, Disk Drill will begin backing up your Mac, making an exact copy of your hard drive on the external drive. This process is time-consuming, so sit back and relax while Disk Drill does the heavy lifting.
Once the copying process is complete, you will have a large DMG file on your external drive that has the name of your main hard drive. This Mac data backup is an exact copy of the data on your hard drive. Everything is included in this file, even live files and 'empty' sectors that need data recovery in order to be read.
Note: if you need to get you clone updated you should create DMG file regularly.
Time Machine is built in to every Mac and is the common way to create incremental backups. You can backup to an external hard drive connected by USB, Firewire or Thunderbolt, or to a supported network drive such as Apple's own Time Capsule. Network-attached storage devices are good places to store Time Machine backups. After you set up Time Machine, it makes backups automatically hourly for the past 24 hours, daily for the past month, and weekly for all previous months.
While Time Machine is the most accessible data recovery tool, it does have its limitations, which make professional robust tools like Disk Drill, Get Backup Pro and ChronoSync Express more attractive:
Time Machine saves your data every hour, though it only keeps the last backup made in a day. Then, it only keeps the daily backups for a month before just keeping weekly snapshots.
It can't create bootable backups. You can only restore damaged drives from the Time Machine archive.
It only works well to backup your primary internal hard drive and will fail for some external and network drives
It has no easily readable, user-accessible log file
It has no diagnostic or feedback system for checking the integrity of your backups.
You can use Time Machine to backup to two different hard drives, or more if you like. Time Machine will rotate the schedule among the drives so that it backs up to each disk in turn and will backup everything that's changed since the last backup was stored on that disk. You can switch disks before entering Time Machine - hold down the Option key, then choose Browse Other Backup Disks from the Time Machine menu. If you work in different locations, you can keep different disks at each location, giving you additional security.
As is the case with most apps, there are options other than Time Machine when it comes to backups. Get Backup Pro is a reliable and versatile utility, giving you a variety of backup choices, including the ability to transfer your data to any computer, regardless whether they have the app.
ChronoSync Express allows you to create backup routines in much the same way as Get Backup Pro – by selecting source and destination and then setting a schedule or running the backup manually.
ChronoSync Express, however, also allows you to do something else: synchronize folders you specify between the source and destination. That means, instead of backing up from one drive to another, and copying either the full drive or files that have changed since the last backup, ChronoSync Express looks at both folders and can copy files in both directions to make sure the folder are identical. And, with the addition of ChronoAgent, the app allows to synchronize files between Macs.
While not a solution for backing up your Mac, ChronoSync is useful if you work on two or more Macs and want to have all your files available on each Mac.
There are good reasons for backing up a Mac to an external hard drive. It's more reliable than wirelessly connecting to a Time Capsule or NAS and more secure than using a cloud service.
You should make sure your external hard drive is at least the same capacity as the disk you want to back up. And use the fastest connection available on your Mac. On newer Macs that's USB-C or USB 3. On older models, Thunderbolt or FireWire.
If you use a Mac laptop, you'll want a portable drive. If not, a desktop external hard drive is perfect. Make sure you erase the drive and format it using APFS if you're running High Sierra or macOS Extended if you're running an older OS version.
Then follow any of the procedures above, either using Get Backup Pro, Time Machine, or ChronoSync Express, and select the external hard drive as the target for your backup.
There are three ways to connect multiple external hard drives to your Mac:
All in all, having a reliable backup strategy should be your priority, as you never know when disaster strikes. Try a few approaches, including apps like Get Backup Pro and ChronoSync Express from Setapp, and find the ideal setup that works for you.
