Time Machine

Time Machine is a Mac utility that allows you to automate hourly, daily, and weekly backups on an external drive that’s connected directly to your Mac or via a local network. It’s seen as the first line of defense against data loss, and features simple setup.

Setting up Time Machine, in its most basic configuration, is extremely easy. All you need to do is launch the Time Machine preferences, turn on Time Machine, select a Backup Disk, and you’re pretty much set.

Of course, there’s much more to Time Machine than just the initial setup, but in this first post in our Time Machine tutorial series for OS X, we’ll cover some of the basic set up options.

Initial Time Machine setup

Time Machine OS X Preferences

Step 1: Connect an external HDD to your Mac. You can also use a Time Capsule, or other form of network attached storage, such as an AirPort Extreme with an external HDD connected via USB.

Step 2: Open System Preferences → Time Machine.

Step 3: Enable the Time Machine switch.

Step 4: Click Select Backup Disk… and select your external disk.

Step 5: Click Use Disk.

Time Machine Select Disk

The first backup will begin in two minutes.

Once the backup begins, you’ll see backup statistics in the Time Machine preferences.

Time Machine Backup Progress

If you have the “Show Time Machine in menu bar” option enabled, you can also check the progress of the backup by clicking the Time Machine menu bar icon.

Since this is my first initial backup using Time Machine, it will probably be large, and thus it will take a while to complete. As you can see from the screenshot above, the first backup is over 200GB. Each subsequent backup should be smaller (and faster), since they are of the incremental variety.

In this example, I used a basic setup that involved connecting a USB 3.0 external drive directly to my Mac. In future Time Machine tutorials, we’ll go more in depth with how to browse backups, restore specific files, local network options, encryption, etc.

    I mostly use carbon copy cloner

    In every tutorial I see online about time machine, I never seem to find an important detail about the HDD. Does the HDD have to be used for the Time Machine? Or can it be used also to store files (maybe with a partition). What happens if I have data on that HDD?

    • Hi

      I have 1 TB hdd i use 600 gigs for time machine and the other 400 for other stuff, just make a partition for your back up.

    • Yes, as stated below it can be partitioned. The data is stored in a designated folder.

  • Scoroncocolo

    I backup to my AirPort Time Capsule.

    Has anyone figured out how to use it as a cloud storage? Not just over wifi, but also over the Internet away from home. I got 3tb and that more than enough to use on my Mac and MBPR.

      You could try doing a NFS mount and do it that way. Idk if it will work but it’s worth a shot.

  • Rupinder

    I bought my Mac about a month ago, and it came with Time Machine installed.

    • BuddhaBr0wnies

      All Mac OSX software comes pre-installed with Time machine 🙂

  • @JeffBenjam:disqus, other than it being free, what is the benefit of Time Machine over a service like Backblaze (unlimited back up for $5 a month)? Isn’t an online back up safer because its not a hard drive that can fail?
