Although iTunes usually does a good enough job backing up your data, the backups are encrypted and inaccessible save for totally restoring your system. What if you want to copy your saved games to a new device? Read on to find out how.

尽管iTunes通常可以很好地备份您的数据，但是备份是加密的，并且无法访问，无法完全还原您的系统。 如果要将保存的游戏复制到新设备怎么办？ 阅读，了解如何。

When it comes to backing up your entire iOS device, iTunes does a pretty decent job and should your device be lost, stolen, or destroyed you’ll be happy to have those backups as a restoration point. When it comes to selective backup and restore, however, iTunes isn’t so hot. Further more it doesn’t always effectively back up 3rd party data. If you’ve spent a lot of time customizing a third party application or you really want to make sure that your Angry Birds run with 3-stars on every level is secure, we’ll show you how.

在备份整个iOS设备时，iTunes做得不错，如果设备丢失，被盗或损坏，您将很高兴将这些备份用作还原点。 但是，在选择性备份和还原方面，iTunes并不那么热门。 此外，它并不总是有效地备份第三方数据。 如果您花了很多时间自定义第三方应用程序，或者您真的想确保在每个级别上与3星一起运行的《愤怒的小鸟》是安全的，我们将向您展示如何进行。

你需要什么 (What You’ll Need)

The requirements for this trick are pretty minimal. You’ll need the following items:

这个技巧的要求非常低。 您需要以下物品：

• A PC or Mac with iPhone Explorer installed.

  已安装iPhone Explorer的PC或Mac。

• An iOS device (iPhone/iPod Touch/iPad) you want to selectively backup data from您要有选择地备份数据的iOS设备(iPhone / iPod Touch / iPad)
• A sync cable同步线

Note: If you want to selectively backup system applications (such as the calendar and email app) you’ll need to have a jailbroken phone in order to secure root access to the system directories. We’re focused on retrieving data from third party applications which do not store their data in the root directory.

注意：如果要选择性地备份系统应用程序(例如日历和电子邮件应用程序)，则需要使用越狱电话，以确保对系统目录的根访问权限。 我们专注于从第三方应用程序检索数据，这些应用程序未将其数据存储在根目录中。

入门 (Getting Started)

We’d recommend plugging in your iOS device and performing a full backup before proceeding. Although we’ve never had any issues backing up and restoring individual application data using the method we’re about to outline it never hurts to have a full backup stashed away.

我们建议您先插入iOS设备并执行完整备份，然后再继续。 尽管使用该方法备份和还原单个应用程序数据从未遇到任何问题，但我们将概述该方法，将完整的备份保存起来也不会有任何伤害。

Once you’ve completed the backup, download and install free application iPhone Explorer. It’s available for both Windows and Mac OS X machines. iPhone Explorer is a great little app for easily browsing the system files on your iOS device. As we noted above, non-jailbroken devices will be limited to browsing the 3rd party data—jailbreak if you want to browse in the root directory.

完成备份后，下载并安装免费的应用程序iPhone Explorer。 Windows和Mac OS X机器均可使用。 iPhone Explorer是一款很棒的小应用程序，可轻松浏览iOS设备上的系统文件。 如上所述，非越狱设备将仅限于浏览第三方数据-如果要在根目录中浏览，则可以越狱。

After installing iPhone Explorer tether your iOS device to the computer via the sync cable. If it automatically mounts in iTunes, dismount it (but leave it plugged in). If iTunes takes control of the device then iPhone Explorer will error out and tell you that the device is inaccessible.

安装iPhone资源管理器后，通过同步电缆将您的iOS设备绑定到计算机。 如果它自动安装在iTunes中，请卸下它(但将其插入电源)。 如果iTunes控制了该设备，则iPhone资源管理器将出错，并告诉您该设备不可访问。

When iPhone Explorer is open you should see a default screen like the one below, minus the “Root Directory” entry (we only see that here because our iPad is rooted).

打开iPhone资源管理器后，您应该会看到一个默认屏幕，如下所示，减去“根目录”条目(由于iPad植根于此，因此我们仅在此处看到)。

Click on the Apps entry to expand the tree. Within the directory tree is the data folder of every third party application on your device. For this tutorial we’re going to find the data for Treasure Island and transfer it off one iPad and onto another. Let’s scroll down and find the data folder. It’s kind of a pain to decode the directory names but typically they’re organizes like com.developmenthouse.appname. Once you locate the directory for the app or game you’re interested in backing up, click on it and simply drag and drop the contents of the folder from iPhone Explorer to a folder on your computer like so:

单击应用程序条目以展开树。 目录树中是设备上每个第三方应用程序的数据文件夹。 在本教程中，我们将查找金银岛的数据，并将其从一个iPad转移到另一个iPad。 让我们向下滚动并找到数据文件夹。 解码目录名有点麻烦，但通常它们是像com.developmenthouse.appname那样组织的。 找到您想要备份的应用程序或游戏的目录后，单击它，然后将文件夹的内容从iPhone Explorer拖放到计算机上的文件夹中，如下所示：

When the transfer is complete you have a total backup of your app on your local machine. Now while you can limit yourself to only backing up individual files you’ve confirmed are the true data files you’re interested in (such as a .SAV or a . LUA file), we recommend starting by copying the entire directory. If you’re ambitious you can mess around with isolating the individual files you need to copy for each specific app.

传输完成后，您将在本地计算机上完整备份了您的应用程序。 现在，尽管您可以限制自己仅备份已确认是您感兴趣的真实数据文件的单个文件(例如.SAV或.LUA文件)，但建议您从复制整个目录开始。 如果您有雄心壮志，可以为每个特定的应用程序隔离需要复制的单个文件。

When the files are safe on your computer you can then archive them or, if you’re in it to copy them, plug in the other iOS device. In this case we’re copying the save files from one iPad to another so we can continue to play the game when the original iPad is out in the field. Plug in the second iOS device and simply reverse the process: navigate to the application data folder and then drag and drop the backup from the computer to the iOS device:

当文件在计算机上安全后，您可以对其进行存档；或者，如果要复制文件，请插入其他iOS设备。 在这种情况下，我们会将保存的文件从一个iPad复制到另一个iPad，这样当原始iPad出场时，我们可以继续玩游戏。 插入第二个iOS设备，然后简单地完成此过程：导航到应用程序数据文件夹，然后将备份从计算机拖放到iOS设备：

There you have it. Whether you’re trying to transfer your Angry Birds high scores and level unlocks between devices or just clone all your Pulse newsreader customizations between your iPads, this technique allows you to reach into your iOS device sans iTunes and backup and restore individual app data.

你有它。 无论您是要在设备之间转移“愤怒的小鸟”高分和级别解锁，还是只是在iPad之间克隆所有Pulse Newsreader自定义设置，此技术都可以使您在没有iTunes的情况下进入iOS设备并备份和还原单个应用程序数据。
