Photos are some of the most important files people want to keep safe. Storing them in the cloud is nice, but you might also want the peace of mind of having your pictures stored locally. Luckily, it’s easy enough to copy your Mac’s Photos library to an external drive.

照片是人們想要保護的最重要的檔案。 將它們儲存在雲中很好，但是您可能還需要放心將圖片儲存在本地。 幸運的是，將Mac的照片庫複製到外部驅動器很容易。

This guide assumes you’re using the actual “Photos” app on your Mac, the default if you’ve used iCloud Photo Stream or imported from your iPhone. If you just have your photos in a folder on your Mac, all you need to do is plug your external drive in and move them over. If you’re using another app that maintains a library, you’ll have to configure things within that app.

本指南假定您在Mac上使用的是實際的“照片”應用程式，如果您使用過iCloud Photo Stream或從iPhone匯入，則為預設設定。 如果您只是將照片放在Mac上的資料夾中，那麼您所要做的就是插入外部驅動器並將其移到上方。 如果您使用的是另一個維護庫的應用程式，則必須在該應用程式中進行配置。

移動照片庫 (Moving Your Photos Library)

To understand how this works, it’s important to know how the Photos app catalogs files. It’s actually simple; there’s a single file that contains your entire library. If you want to back this up, you plug in your external hard drive and drag the whole file over to that hard drive in the sidebar of Finder.

要了解其工作原理，重要的是要了解Photos應用程式如何對檔案進行分類。 實際上很簡單； 有一個包含整個庫的檔案。 如果要備份此檔案，請插入外部硬碟驅動器，然後將整個檔案拖到Finder邊欄中的該硬碟驅動器上。

The harder part comes when you need to change which Photos library you want to use. You’ll have to change the location from which the Photos app is reading.

當您需要更改要使用的照片庫時，困難的部分就來了。 您必須更改“照片”應用的讀取位置。

In the image below, I’ve got two Photos libraries, the default one, and a backup library.

在下圖中，我有兩個照片庫，預設的一個和一個備份庫。

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.

雖然您可以通過雙擊備份庫來訪問備份庫(這將在Photos應用程式中將其開啟)，但最好將Photos切換為預設使用此庫。 您總是可以在需要時切換回常規庫。

Double click the backup library to open it, then open the preferences for Photos from Photos > Preferences in the menubar.

雙擊備份庫將其開啟，然後在選單欄中開啟“照片>偏好設定”中的“照片”偏好設定。

Select “Use as System Photos Library,” which will change the default to the new library.

選擇“用作系統照片庫”，它將預設設定更改為新的庫。

使用Time Machine自動備份驅動器 (Back Up Your Drive Automatically With Time Machine)

Backing up files manually is not the best solution, as you can never predict when your computer will break. It’s better to back up automatically, so you don’t have to think about it at all. Apple’s built-in Time Machine is the best tool for backing up to an external drive. You can read our guide on setting it up to get started.

手動備份檔案不是最佳解決方案，因為您永遠無法預測計算機何時會損壞。 最好自動備份，因此您完全不必考慮它。 蘋果內建的Time Machine是備份到外部驅動器的最佳工具。 您可以閱讀我們的設定指南以開始使用。
