Here's a guide on how to How to Set Up Time Machine Backups in Mac OS X.

But before you proceed to the guide, see below some requirements for the Time Machine Backup.

Time Machine Backup Requirements
  • Any Mac with any vaguely modern version of OS X (El Capitan, Yosemite, Mavericks, Mountain Lion, Snow Leopard etc)
  • A large External Hard Drive (this one is 5TB) which will be dedicated to Time Machine and connected to the Mac
  • Format the drive to be Mac compatible with Disk Utility, give it an obvious name like ‘Time Machine backups’
  • A few minutes for initial Time Machine setup
  • Ample time for Time Machine to run it’s first backup of the entire Mac
How to Set Up Time Machine Backups in Mac OS X

1. Connect the external hard drive that you’ll be using as a Time Machine volume to the Mac if you have not done so already

2. Go to the  Apple menu and go to “System Preferences”, then choose “Time Machine”


3. Click on the “Select Backup Disk…” button


4. Choose the connected external hard drive that you plan on assigning to Time Machine, then click on “Use Disk”


5. The “Time Machine” toggle should now be set to ON and you’ll see some backup data like the size of the backup, how much space is available on the target Time Machine volume, oldest backup, latest backup (both of which will be none on a fresh drive), and the next backup countdown – when the two minute countdown hits zero the first Time Machine backup will begin, let it start and finish


* Optional but recommended, toggle the switch for “Show Time Machine in menu bar”

The very first time you run Time Machine can take quite a while to backup the entire Mac, because it’s literally copying every single file, folder, and application from the Mac to the Time Machine volume as a complete backup.
