Making a backup copy of all files on Mac, including your iTunes songs is necessary to avoid losing important data that you cannot retrieve easily. Photos, documents and videos are just three of the many things that you might want to consider making copies. Even if your Mac is fairly new, you still need to backup, every now and then.
With the new operating system, it is now easier to backup your files, and it is for free. Follow the steps below to help you out:
Obtain an external hard drive
You will need an external hard drive, where you can put all files that you want to make copies. These days, external hard drives are no longer deemed expensive. You can purchase 500 GB drive at a very affordable rate.
Configure Time Machine
Time Machine is a built-in backup feature of Mac OS X. When you plug in the external hard drive the first time to your Mac, said app will ask if you want to use it to make backup copies.
If so, click the Use as Backup Disk option. This will lead you to the app’s preferences. It will automatically perform your first backup. Each time you plug the hard drive into your Mac, it will perform such operation. It’s basically the same as when you use an iTunes duplicates remover.
Tweak the app
Sometimes, there are files that you do not need to backup. You can exclude certain items to help you conserve disk space on your hard drive.
To exclude some items, you need to hit the Options button found in the Time Machine window.
Click the “+” sign to add files and folders to the list of Do Not Back Up.
If you do not want to include your Applications folder, simple choose your computer’s hard drive, click the Applications folder and hit the Exclude button.
Start the backup
When everything is fine, Time Machine will now start making backup copies of the data you have on your Mac. The first backup process can take minutes to hours.
