macos备份恢复

If you’re installing a new hard drive, or your Mac is completely messed up, you might think it’s time for a fresh installation of macOS. But if you’ve got a Time Machine backup, that’s not necessary: you can fully restore your Mac, and have all your applications and files exactly as you left them.

如果要安装新的硬盘驱动器，或者Mac完全被搞砸了，您可能会认为是全新安装macOS的时候了。 但是，如果您有Time Machine备份，则没有必要：您可以完全还原Mac，并完全保留所有应用程序和文件。

We’ve shown you how to back up and restore macOS from Time Machine, but today we’re going to dive in a little more and show you how restoring from Recovery Mode looks. Let’s dive in!

我们已经向您展示了如何从Time Machine备份和还原macOS ，但是今天我们将进一步探讨如何从“恢复模式”还原。 让我们潜入吧！

第一步：进入恢复模式 (Step One: Boot Into Recovery Mode)

The first thing you need to do is access Recovery Mode. Shut down your Mac, and then hold down Command+R while turning your Mac back on.

您需要做的第一件事是访问恢复模式。 关闭您的Mac，然后在重新打开Mac的同时按住Command + R。

Note that this only works if you have a recovery partition, which you will not have in the case of a new hard drive. Don’t worry: you can boot into macOS recovery without a recovery partition using another keyboard shortcut: Option+Command+R.

请注意，这仅在具有恢复分区的情况下有效，而在使用新硬盘驱动器时则不会。 不用担心：您可以使用另一个键盘快捷键Option + Command + R进入没有恢复分区的macOS恢复。

Either way you should eventually boot into Recovery Mode. On the utilities screen, select the “Restore From Time Machine Backup” option.

无论哪种方式，您最终都应该启动到恢复模式。 在实用程序屏幕上，选择“从Time Machine备份还原”选项。

On the Restore From Time Machine page, hit the “Continue” button.

在“从Time Machine还原”页面上，单击“继续”按钮。

第二步：选择硬盘 (Step Two: Choose Hard Drive)

Next, you’ll be asked which Time Machine drive you’d like to recover from.

接下来，将询问您要从哪个Time Machine驱动器恢复。

Connect your USB drive, if you’re using one. If you’re restoring from a network drive, you may have to connect to a wireless network before proceeding. A wired connection will be lot faster, so if that’s an option use that instead.

如果使用USB驱动器，请连接它。 如果要从网络驱动器还原，则可能必须先连接到无线网络，然后再继续。 有线连接会快很多，因此如果可以选择的话，请改用有线连接。

Also note that restoring from an encrypted Time Machine backup will require the password.

另请注意，从加密的Time Machine备份还原将需要密码。

第三步：选择备份 (Step Three: Choose Backup)

After you’ve chosen a drive to restore from, it’s time to choose which backup to use.

选择了要还原的驱动器之后，就该选择要使用的备份了。

If you backup multiple Macs to a single drive you’ll need to pick your computer from the “Restore From” dropdown. Next, pick which time you’d like to restore from. If you’re setting up a new hard drive it’s best to pick the most recent one, but if you’re recovering from a crash you should pick a backup from before you started having problems.

如果将多台Mac备份到单个驱动器，则需要从“还原自”下拉列表中选择计算机。 接下来，选择您要还原的时间。 如果要安装新的硬盘驱动器，最好选择最新的硬盘驱动器，但是如果要从崩溃中恢复，则应该在出现问题之前从中选择一个备份。

Make your selections, and then click the “Continue” button to begin the restore.

进行选择，然后单击“继续”按钮开始还原。

This may take a while, especially if you’re restoring from a network backup, but when it’s done you’ll have all of your files.

这可能需要一些时间，尤其是如果要从网络备份还原时，但是完成后，您将拥有所有文件。

替代选项：重新安装，然后使用迁移助手还原 (Alternative Option: Install Fresh, And Then Restore With Migration Assistant)

In some cases the above method will fail, but don’t panic: you can still recover your files. Simply install macOS from scratch, and then use Migration Assistant to transfer all your files from a Time Machine backup. Your Mac will offer this tool after installation is complete, or you can run it manually after installation is complete.

在某些情况下，上述方法会失败，但不要惊慌：您仍然可以恢复文件。 只需从头开始安装macOS ，然后使用Migration Assistant从Time Machine备份中传输所有文件。 Mac将在安装完成后提供此工具，或者您可以在安装完成后手动运行它。
