Today's digital cameras and advanced smartphones like the iPhone 6 take stunningly detailed photos, but all that extra resolution comes at the price of larger image files. Moving part or all of your iPhoto Library to an external hard drive is one of the most effective ways to free up precious space.



Before starting the process, we suggest making an up to date Time Machine backup of your computer to an external hard drive or Time Capsule. Be sure the external hard drive you use to perform this backup is a separate unit from the one you will move the iPhoto Library to should anything happen.
If you have an account with a cloud storage service, such as Dropbox, Google Drive or even iCloud Drive, you can also upload the iPhoto Library to these services for extra redundancy.


To begin moving your library, open iPhoto, click File in the Menu Bar and select Switch to Library.


A new window will appear listing any and all iPhoto Libraries detected on your computer. If you're not sure where the iPhoto Library file is located, look at the (Default) listing and the file path will be listed underneath. This should be located in the Pictures folder of your Home directory.


Quit iPhoto by going to Quit iPhoto in the iPhoto Menu Bar or pressing Cmd+Q. Connect the external hard drive that you will use to copy the iPhoto Library. You should see it appear on your desktop.


Open a new Finder window and click Pictures in the left sidebar. Click and drag the iPhoto Library file onto the external hard drive icon on your Desktop.


Depending on how large your library is and the connection speed of the external drive, it may take several minutes or longer to complete the copy process.
Once the copy is completed, hold the Option key on your keyboard and open iPhoto from the Dock or Applications folder. A new window will pop up asking you to Create a New Library, Choose the Selected Library or Other Library. Click on Other Library.


In the browser window that appears, navigate to your external hard drive, click the iPhoto Library file you've copied and click Choose.
iPhoto will open and as long as the external hard drive is connected, will reference the library on the external drive and not on your computer's drive.

Quit iPhoto once again and eject the external hard drive holding your new iPhoto Library. Open a new Finder window and navigate to the Pictures folder in the left sidebar again.
Right click or Ctrl+click on the iPhoto file and move it to the Trash.


How To Backup Photo Library Mac To External Hard Drive Access Denied

Finally, to free up the space on your internal hard drive, open the Trash from the Dock or Finder window and click Empty Trash in the upper right corner.


Your iPhoto Library has officially been removed from the internal drive. You can now reconnect the external hard drive you used to copy the iPhoto library, open iPhoto and use it as normal.
If you open iPhoto without your external hard drive connected, iPhoto will give you an error message saying the 'Library cannot be found.' Quit iPhoto, connect the external hard drive and reopen to fix.

Apple's iCloud Photo Library service works seamlessly to sync and back up your images and video across all of your Apple devices to iCloud — but if you're serious about keeping your irreplaceable photos and video safe, you'll want a redundant (second) backup. Because as they always say, you can never have too many backups! And it's better to be safe than sorry, honestly.

Backing up your photos can take the form of a local backup on your own drive or an external source, a secondary online backup, or both. Here's how to do it all.

How to back up iCloud Photo Library to your Mac's hard drive

The best way to back up the images and video in iCloud Photo Library is to make sure you're downloading all your content onto your Mac.

Note: If you plan to back up your entire digital library to your Mac's hard drive, you'll likely want to do it on a desktop Mac with a 1TB drive or higher. Otherwise, consider backing up to an external drive.

  1. Launch the Photos app on your Mac.

  3. Select Preferences from the drop-down menu.

  4. Click the iCloud tab.

  5. Click Download Originals to this Mac.

How to back up your iCloud Photo Library content to an external drive

There are two ways to back up your iCloud Photo Library to an external drive: by backing up your Photos library automatically, or manually. (You can also export sections of your library if you don't want to back up the whole thing.)

Back up your Photos library automatically

If you've turned on the Download Originals option for your Photos library, you can back up your Photos library as part of your regular backup routine. Whether you use Time Machine or clone your hard drive using SuperDuper! or Carbon Copy, your Photos library (and all images and video automatically downloaded from iCloud) will be backed up as well. (And if you don't currently use a backup service, well.. now's a good time to start!)

Back up your Photos library manually

If you've turned on the Download Originals option for your Photos library but don't want to back it up automatically, you can always copy your Photos library to an external drive at regular intervals.

  1. Connect an external drive to your Mac via USB, USB-C, or Thunderbolt.

  2. Open a new Finder window on your Mac.

I recommend setting a bi-weekly reminder for these steps, so you keep your Photos library regularly backed up.

How to back up portions of your iCloud Photo Library

Don't want to back up your entire library? You can export individual images and videos to your external drive.

  1. Connect an external drive to your Mac via USB, USB-C, or Thunderbolt.

  2. Open the Photos app.

Back up the library in Photos on Mac. Even if you use iCloud Photos, it’s important that you always back up your library locally using one of the following methods.

How to make an online backup of your iCloud Photo Library

Even though your entire iCloud Photo Library is (as the name implies) stored online in iCloud, it's worth considering a second online backup as one of your redundancies.

If you store your entire iCloud Photo Library on your Mac

Good news: If you already use a service to back up your hard drive and you've synced your full iCloud Photo Library to your Mac, it's easy to back it all up. (If not, consider it a good time to start!)

If you don't store your iCloud Photo Library on your Mac

If you don't store your iCloud images locally, this is a bit trickier: you can use the external drive method to export portions of your library to an external drive, then sync that drive to your preferred online backup service, but it's a bit more labor-intensive. In general, this is why I tend to recommend backing up your full library to your Mac or storing a library on an external drive.
