How to fix a corrupt iTunes backup and restore its data

Alexandra Malureanu

由 Alexandra Malureanu

Recovering data from a corrupt iTunes backup is difficult but not impossible, and messages like "backup is corrupt or not compatible with your iPhone that is being restored" don't mean your data is "irreversibly lost". You've got a great chance of recovering corrupt backups automatically with iPhone Backup Extractor.

Corrupted iTunes backup? You can recover your data...
iTunes备份损坏?你可以恢复你的数据......

It's usually straightforward to recover data from an unencrypted corrupt iTunes backup. Encrypted corrupt backups are trickier, especially if the "manifest files" are missing, as these describe how data in the backup was encrypted, and are essential for the decryption process.

Backups can be corrupted to different extents. For example, running out of disk space in the middle of a backup, having a hard-drive fail (or Dropbox eating your files!), an iOS upgrade going wrong, or a power failure during the backup can each affect the backup in different ways.

There are handful of errors you might get when a backup is corrupt. Let's look at the cause and solution to each.

iTunes restore errors that indicate corruption

iTunes无法恢复iPhone,因为备份已损坏或与正在恢复的iPhone不兼容

第一条消息很简单,告诉您正在处理损坏的备份。当iTunes正在备份您的iOS时,可能会发生此过程失败而没有错误消息。只有在尝试使用iTunes进行恢复时,才会发现您的备份已损坏。获取您的数据并不困难:查看我们的指南,从下面的损坏的iPhone备份中获取数据,

iTunes无法恢复[iPhone],因为备份会话失败

This error is similar to the first, and also tells that you are dealing with a corrupt or unfinished iTunes backup. The cause is similar. See our tips on recovering data from corrupted backups below.

iTunes无法恢复,因为iTunes无法识别您的设备

第三条消息要求您检查是否使用最新版本的iTunes,USB电缆连接正确(并且没有损坏),并且您没有任何第三方软件干扰iTunes。

如果上述方法无效,则通常可以使用恢复模式解决此问题。恢复模式将清除您的设备并将其恢复:如果您之前与iTunes或iCloud同步,您将能够在恢复后从备份恢复。

最糟糕的情况是,您正在连接的iOS设备存在根本问题。如果 - 并且您有备用设备 - 请尝试使用它。如果做不到这一点,我们可以帮助您从损坏的iTunes备份中提取数据。继续阅读!

iPhone无法恢复。出现未知错误

对于一系列不同的问题,这个错误是一个包罗万象的问题。根据潜在原因,有许多解决方案:

  • 使用最新版本的iTunes(而不是测试版!)是一个很好的起点 - 升级,如果你尚未使用它
  • Windows用户可以找到重启帮助(如果您按照上面的步骤并升级iTunes,则无论如何都需要重启)
  • 完全重置手机并在DFU模式下运行恢复
  • 苹果发布一个简短的文件有进一步提示这个错误

如果你在这里不能成功,请查看我们的指南,从下面的损坏的iTunes备份中恢复数据。

连接到iPhone需要软件更新

此消息表示您需要更新才能连接到iPhone,并且消息中不清楚是否需要更新您的PC或Mac或iPhone。这是它所指的计算机。

A software update is required to connect to iPhone
连接到iPhone需要软件更新

如果用户运行的是iOS测试版,但未运行等效的iTunes测试版,则用户通常会获得此信息。如果是这种情况,点击“安装”按钮将不起作用。它会说它在失败之前下载了一段时间,说“安装失败。无法安装软件,因为它目前无法从软件更新服务器上获得”。解决方案是安装最新的iTunes测试版。

4个技巧来修复损坏的iPhone备份并检索您的数据

iPhone备份提取器旨在帮助您在无法通过iTunes正确还原备份时获取数据。它打开iTunes和iCloud备份并提取有价值的数据 - 即使该备份已损坏。

1.使用iPhone Backup Extractor的内置损坏处理

甚至免费版的iPhone Backup Extractor也内置了很多聪明的功能来处理损坏的备份,它可能会正常提取您的数据。

尝试从“概述”中获取数据提取的快速链接,并查看有关恢复iTunes数据的常规指南。

如果概述没有生成您需要的内容,则还有另外两种方法可供尝试。

  1. 检查“预览”选项卡以查看数据是否可用于提取。如果有数据,您可以单击应用程序的名称,选择所需的消息,然后以所需的格式提取它们。如下:

    Previewing messages
    预览消息

  2. 使用“提取”菜单将可用消息导出为HTML或CSV,如下面的屏幕截图所示:

    Extracting messages with the file menu
    使用文件菜单提取消息

即使上述步骤不起作用, 仍然可以从损坏的备份中检索联系人,消息和照片等数据。不要放弃希望 - 让我们更深入......

2. Use expert mode to recover iPhone data from individual files

如果直接方法不适合您,您仍然可以使用“专家模式”和“应用程序视图”从备份中恢复文件。联系人,日历,SMS消息,位置和备注等数据存储在备份中的特定文件中,并且 - 如果您将文件丢弃 - iPhone备份提取器可以将它们转换为可读格式。

使用iPhone Backup Extractor加载备份,然后在“专家模式”中导航以选择代表所需数据的文件。我们有一篇关于应用程序将数据存储在iTunes备份中的文章,这在知道查看位置时会很有帮助。

获得必要的文件后,可以将其转换为可读格式:

  1. 单击iPhone备份提取器中的“文件”菜单

  2. 选择“将消息数据库转换为CSV”,“将联系人数据库转换为vCards”或任何最适合您文件的选项

    Using the file menu to convert...
    使用文件菜单转换...

  3. 该应用程序将导出您的联系人和消息。

    Recovery successful!
    恢复成功!

3.为照片和视频筛选未加密的iPhone备份

即使iTunes进程不完整并导致备份文件损坏,您仍可以在iTunes备份中找到照片和视频。为了使其工作,需要使用加密创建备份。

尝试这个:

  1. 找到有问题的备份文件夹(您可以在iPhone备份提取器中右键单击备份,然后选择“显示封闭文件夹”)

  2. 制作整个文件夹的副本 - 我们将对其进行大量修改......

  3. 按大小对文件内部进行排序,并删除所有小于300KB的文件

  4. 下载并安装批量重命名实用程序 - 它是免费的,非常适合我们在这里需要的东西

  5. 打开“批量重命名实用程序”并导航到您创建的备份文件夹的副本,然后选择它

  6. 使用Add > Suffix (7)菜单将jpg (无点)添加到Extension Section (11).jpg (带点)

  7. 选择顶部窗口中的所有文件(它们将显示为绿色)

  8. 单击“重命名”按钮,然后将所有选定的文件重命名为jpg文件

    Bulk Rename Utility in action
    批量重命名实用程序正在运行中

  9. 在保存它们的文件夹中,在Windows资源管理器或macOS Finder中选择“缩略图视图” - 现在您应该可以看到哪些文件是照片,因为它们将与预览一起显示

  10. 将恢复的照片移动到一个安全的新文件夹,然后使用其他文件扩展名(例如.mov.heic重复步骤#5中的过程,直到您将它们全部恢复为止

4. Rely on Reincubate's experts to do it for you

I just got had to swap my phone due to issues on the phone when I try to restore from my backup it say corrupted or not compatible

Oh no! Have you followed the steps in the guide? If so, and you're still stuck, drop us a note or ping us on live chat. 🙂

I need a way to extract music and eBooks from a corrupt backup, any ideas?


Hey Robert. iTunes' music isn't stored in a backup, and won't be available there. However, eBooks are, and so is music from many third-party apps. Which apps are you using for the books and music?

How do you extract a voice memo from a corrupted backup?

Thanks!

The simplest way is just to click "Recordings" on the main iPhone Backup Extractor window when your backup is selected. Alternately, you can find them in iPhone Backup Extractor's "Expert mode" in the folder described here.

Is it possible to restore messages back on an iPhone

Hey Kevin, there sure is: check out this guide.

Got a new iPhone 6. Tried to restore it from iTunes. No backups were found in ITunes. Found the backup folder on my PC but three of the .plist files are missing. Status.plist is the only one I have and it looks incomplete. Need some help..


Uh-oh, missing files indeed. Drop us a note and we'll guide you through recreating those missing files.

My Iphone backup was corrupt. Please help me to restore data. I found physical stored data (10GB) on my lop top. I need help to backup this data on my iphone 5. There are very important files: app - gflash, and my contacts. Please help me to restore data. Thank you a lot.


Hi Andre, no problem. The guide above should help with accessing the backed up data, and this guide should help you restore is. Does that help?

I am trying to recover some lost voicemails using iExplorer. There are 4 backups to my phone and all are damaged. Is there a way to fix that or get the voicemails back from the damaged backup file? Any help you could give me would be greatly appreciated. The voicemails are from my gramma who passed away. Thanks.

Yes, try iPhone Backup Extractor. If it won't automatically recover them for you, ping us on live chat and we'll help you get them back manually.

Hi,

I'd extracted out all the files, but how can I restore inside my phone?

Hi Elsie, we've got a guide for that here.

Good day

I would be very grateful fr a workaround for the issue I face, please. I removed the cable, like an idiot, during a backup process, it was third party software (iBackupBot) and the progress indicator had been stuck at zero for several minutes, i panicked. Right now, I can't back up to or from my device, I am pretty sure it is a corrupted manifest file. Please could you direct me to workarounds for this error:

Invalid name size [E9B1] at [30E77]:
(null)
Prev Domain:C:\Users\........
/manifest.db
Prev Path:CameraRollDomain

I realise I have probably boxed this thing, is it even possible to restore a new iOS version?

Thank you in advance Morgan

Hi Morgan, that sounds nasty! We're not experts on iBackupBot, but we can certainly help with your phone. Have you tried a factory reset?

Hi, hope you can help me. I backed up my old iPhone 5 on iTunes in my laptop as the phone has a hardware defect and needs to be replaced with a new unit. I made sureall was backed up in itunes. I now got the new unit and attemptied to restore the data backed up from the old unit, however, the data restore in iTunes is greyed so I assume the data was lost. Is it still possible to recover all the lost data back up?

Hey Avenshen, I'd guess that's because the newer device is on an older version of iOS than your newer one. If that's the case, an update will resolve the issue. If not, drop us a note and we'll get you sorted out.

hi! The files of my ipad get deleted. I already try the backup in itunes, but I dont have any backup there. All files are very important to me. Please help me. THANKS!

Hi Carlo, that doesn't sound good. Have you manually checked your iTunes backup folder? There's guidance on how to find them, here. Failing that, do you have a a backup of your computer in Time Machine, or another backup service?

good morning, my backup(11 G0) is incomplete and encrypted, i have the password. Do your soft can extract any data?

It certainly can. Try the free version linked to the side of this page, and reach out if you need help.

my ipod does not work as it says my ipod back-up has been corrupted and i am unable to sync with itunes

Reach out to us directly on live chat and we'll guide you through it with a screen-share. 🙂

What if I only can find status.plist? The info.plist, manifest.plist and the manifest.mbdb is missing. Is there any way to recreate them?


Hi Johan: yes. Move your backup out safely to another folder, and then create a new backup. If the device contents are similar enough, you may be able to reuse those files. Good luck!

Hi,

I have updated my iphone to ios7 beta release and later on downgraded back to ios 6.1.3. But restore backup is not compatiable. Tried after changing Product version and Build Version in Info.plist. But now it says data is corrupt or not compatiable.

Please help me to restore my backup data


Right, this is a problem for a number of users. We can help you patch your messages etc. back into your older database if you drop us a message directly.

Hi, some how my iphone backup got corrupted. And so I tried to restore it with another back up, but it was my ipod backup and when i tried restoring it back it said "itunes could not restore the phone because the phone refused the request" and this is frustrating because it wont let me send any messages and all my contacts and stuff are gone.

Hey Devin, drop us a note and we'll give you a hand with your backup. There'll be a way!

i want to simply reset my iphone pin to purchase apps for the phone.

i dont require resetting my ios and i dont want to affect the ios, but can iphone extractor reveal the pin if i run it?

Dominic: see our article on resetting the restrictions passcode for a solution to this.

My iPad had begun to have more and more apps crashed so I took it to the apple store. The genius read the incident report and said I had corrupt files so I needed to plug it into my MacBook and backup it up then reset the device. He said since the file would also be corrupted on the backup that I would need to start new instead of restore the backup.

I did so and now I have a few apps that I have lost data from. I have since been informed that one app can't corrupt the whole iPad because of sandbox. So who do I believe and how do I proceed? I did try restoring the iPad's backup and the problem was still there so I reset and made new and that's where I'm at now.

Oh no! That's frustrating. Drop us a note directly and we'll help you recover that data. It shouldn't be possible for any of your iOS apps to corrupt your backup.

Hi,

My last backup of my iPhone 5 somehow got corrupted after a failed iOS 6.0.2 upgrade.

I can see all the files in the backup folder but it is missing all the manifest files.

I use iPhone Backup Extractor to review the Backup file and it doesn't recognize the last backup taken before the upgrade.

I would like to know is there a way to recover the last backup?

Thanks Nighto

Nighto, this is because the previous backup can sometimes get overwritten after the upgrade (Yes, I did say after! And yes, this does happen ever now and then). Without the manifests it can cause issues reading files, but iPhone Backup Extractor can certain find data without the manifests by using the File menu. However if data does exist in the backup, we are experts at extracting, so please contact our help desk for more information.
