Photos are some of the most important files people want to keep safe. Storing them in the cloud is nice, but you might want to have peace of mind. Luckily, it's easy to copy your Mac's Photos to an external drive.
This guide uses the actual "Photos" app on your Mac, the default iCloud Photo Stream or imported from your own iPhone. If you just have your photos in a folder on your Mac, all you need to do is plug in your external drive and move them over.
Moving Your Photos Library
To understand how to do this, it's important to know the photos app catalogs files. It's actually simple; there's a single file that contains your entire library.
The harder part comes when you need to change which Photos library you want to use.
In the image below, I've got two photos libraries, the default one, and a backup library.
While you can access the backup library just by double-clicking it-which will open it in the Photos app-it's better to switch Photos to use this one by default. You can always switch back to the regular library when you need to.
Select Automatically With Time Machine
Backing up files manually is not the best solution want to break. Apple's built-in Time Machine is the best tool for backing up to external drive. It's better to back up automatically. You can read our guide on setting it up.
