How to Make a Backup Mac

You have recently purchased a Poppy and are you looking for valid solutions to backup your data? Have you decided to change your Mac hard drive and don't know how to transfer the data from your old drive to the new drive you bought? Then I guess you've come to the right place at the right time!

With today's guide, in fact, we will see together how to make a Mac backupusing two distinct solutions: one included "standard" in macOS, which allows you to copy your data constantly on an external disk and always have them available in case of need, and an external one, which instead allows you to "clone" the entire contents of the disk to another drive and to boot from that drive (which does not allow the Mac default solution).

Both software are very easy to use and do not require any particular configuration: once you have chosen the initial backup parameters, just let them work and they do everything by themselves. So, can you know that you are waiting to get started? Take five minutes of free time, choose the solution that seems best suited to your needs and follow the instructions I am about to give you. You will see, creating a backup of your Mac is really a breeze!

Preliminary Operation

Before seeing in detail how to make a backup on Mac, you have to get a suitable disk to do this and you have to format it correctly, using the file system Mac OS Extended journaled.

As can be easily understood, the disc you need to get must have one capacity equal to or greater than the Mac disk. A drive with even double the capacity of the Mac's disk would be recommended (in order to keep multiple backup copies of your data), but of course it's up to you to choose based on your needs and budget. However, if you want advice on which hard drive to buy, you can consult my buying guide dedicated to external hard drives.

To format the disk with Mac OS Extended journaled file system, connect the drive to the USB port of the computer, start theDisk Utility macOS (located in the Other . Launchpad) and select the backup drive from the left sidebar.

At this point, click on your button Initialize located at the top center, set the item Mac OS extended (journaled) on the menu Format, type il name you want to assign to the hard disk (eg. TIME MACHINE) in the appropriate text field and first click on the button Initialize and then end to complete the formatting procedure. The process will take a few seconds and will completely erase the contents of the disk, so make sure you have no important data saved on the drive before starting it.

time Machine

Now let's see how to make a backup of the Mac in a "traditional" way, taking advantage of the excellent time Machine: the backup tool included "standard" in macOS.

Time Machine automatically copies all the files, applications and settings on the Mac to an external hard drive. Using it, you can recover files deleted by mistake, restore them to an earlier date and restore the entire system in case of problems. When the backup disk runs out of space, the application will intelligently delete older files without you having to lift a finger.

Back Up with Time Machine

To find out how to make a backup with Time Machine, all you have to do is connect to the Mac the hard disk on which to save the backup copies of the files and wait for macOS to ask you if you want to use the device as a backup disk. Then answer in the affirmative by clicking on the button Use as a backup disk, and the Mac will automatically start copying all data on the computer to the external hard drive.

If you want to set a password to protect your backups (and therefore require the entry of the same in case of data recovery), put the check mark next to the item Backup disk encryption and then type the keyword you want to use in the window that opens.

At this point, you do not have to do anything more: Time Machine will automatically perform its backups whenever the drive is connected to the computer and will manage all the data in an intelligent way, updating and adding to the existing backups only the necessary data ( incremental backup).

If there was no prompt from Time Machine when you connected the drive to your Mac, do the following: Open System preference (the icon ofgear located in the Dock bar), click on the entry for time Machine, pigia sul pulsating Select backup disk, choose the disk to use for backup and click on the button Use the disc. Make sure there is a check mark on the entry as well Back up automatically in the left sidebar.

Again, if you want, you can put the check mark next to the item Codifica i backup to activate the password request for restoring data from backup.

If you need it, know that Time Machine allows you to make backups even on disks connected to the network. All you have to do is connect the disk on which you want to backup to the router you use to connect to the Internet and connect the Mac to the network generated by the latter.

If you have a router AirPort Extreme 802.11ac di Apple, you need to make sure that the disk partition intended for backup is set to accept the data condition. Start, then theUtility AirPort on your Mac (located in the Other Launchpad), click on the name of theAirPort Extreme and then on the button Modification to access the device settings (if this is your first time doing this, you may be asked to unlock the router by entering its password).

In the window that opens, go to the tab Discs, choose the disk or partition you want to use with Time Machine, put the check mark next to the item Enable file sharing and presses the button Update to save the changes. The same procedure also applies to Time Capsule, Apple's routers with integrated hard drives.

Note that if the backup disk is on a network, the network server must use file sharing Apple File Protocol (AFP) and both the Mac and the backup disk must have macOS 10.5.6 or later. For more details on this, consult the Apple website.

Restore a Backup with Time Machine

Once your backup is created, you can use Time Machine to restore previous versions of files and folders that you have on your computer disk (or bring back deleted data from the disk "to life").

To take advantage of this possibility, open the Finder (the smiling face icon located on the Dock bar) and go to the path that contains, or contained, the folders and files you want to restore. At this point, click on the icon time Machine located at the top right, in the macOS menu bar (the clock next to the system clock) and select the item Entra in Time Machine from the menu that appears on the screen.

You will be shown a (very choreographic!) Screen with the folder you opened in the Finder in the center and one on the right time bar, through which to select the backup to restore. Then right-click on the file or folder you want to restore, select the item Reset [file or folder name] to from the menu that opens, choose the destination to copy it to and that's it.

Please note: if you don't see the Time Machine icon in the macOS menu bar, go to System Preferences> Time Machine and apponi il segno di spunta accanto alla voce Show Time Machine in the menu bar.

Reset the Mac with Time Machine

If necessary, Time Machine backups can also be used to restore the entire system, returning it to the state it was in on the date of the chosen backup.

To take advantage of this, you need to start your Mac in recovery mode (by holding down the key combination cmd + r while turning on the computer, until the bitten apple logo appears on the screen). After that you have to select the item Use Italian as your primary language, click on the button (->) and connect the Time Machine backup disk to your Mac.

At this point, fai clic sulla voce Restore from Time Machine backup, pigia sul pulsating Continue twice in a row, choose the backup disk, go ahead, choose the date of the backup to restore and click again on Continue.

Finally, select the Mac diskclick on your button Unlock to unlock it by typing the macOS administration password and click on the button Restore. The system restore procedure will take quite a while.

For more information, if any of the steps are not clear to you, you can consult my tutorial on how to backup with Time Machine, in which I explained in more detail how to use the backup system included in Macs.
