在Windows 11/10中备份文件时，如果您遇到备份错误 0x8100002F^{(Backup error 0x8100002F)}，那么这篇文章可能会有所帮助。当您尝试复制系统文件或创建系统映像时，或者当Windows尝试备份联系人中的文件时，或者如果系统找不到指定的文件时，可能会出现此类Windows备份错误。这篇文章中介绍了一些简单的修复程序，可能会解决此错误。

Windows 备份^{(Windows Backup)}错误代码 0x8100002F

1. 运行 CHKDSK
2. 运行系统文件检查器^{(Run System File Checker)}或DISM工具
3. 使用注册表编辑器
4. 移动导致错误的文件或文件夹
5. 使用外部磁盘进行备份
6. 使用第三方工具进行备份。

1]运行CHKDSK

CHKDSK是^(CHKDSK)Windows 10中的内置实用程序，可帮助检查硬盘驱动器是否存在错误、坏扇区、运行状况、系统文件问题，然后尝试修复此类问题。这也可能有助于消除备份错误 0x8100002F。因此，为两个驱动器（源和目标）运行CHKDSK实用程序并完成该过程。^(CHKDSK)这应该有效。

2]运行系统文件检查器^{(Run System File Checker)}或DISM工具

系统文件检查器^{(System File Checker)}( SFC ) 和DISM工具都是Windows 11/10的内置功能。虽然第一个有助于查找损坏的系统文件并修复它们^{(find corrupt system files and repair them)}，但 DISM 工具有助于修复 Windows 映像文件^{(repair Windows Image File)}和 Windows 组件存储。

您可以使用系统文件检查器或使用命令提示符^{(Command Prompt)}窗口运行 DISM^{(run the DISM)}工具。让扫描和修复过程完成，然后尝试启动Windows备份。

3]使用注册表编辑器

可能有一些用户配置文件键不应该出现在注册表编辑器^{(Registry Editor)}中。因此，删除此类密钥可能会解决您的Windows备份问题。在尝试此选项之前，您应该备份注册表编辑器^{(backup Registry Editor)}，以便以后发生错误时可以恢复它。现在按照以下步骤操作：

• 打开注册表编辑器
• 转到ProfileList注册表项。路径是：

HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > Windows NT > CurrentVersion > ProfileList

• 选择ProfileList键下的文件夹
• 在右侧，查找ProfileImagePath字符串值
• 如果该值存在，则该用户配置文件文件夹正常
• 如果该值不存在，则删除整个文件夹
• ^(Repeat)对ProfileList文件夹下的其他文件夹^{(ProfileList)}重复上述所有步骤。

4]移动^(Move)导致此类错误的文件或文件夹

有时，它只是导致此类错误的文件或文件夹。例如，大多数用户在复制用户配置文件下的联系人文件夹时都会遇到此错误。^(Contacts)在这种情况下，只需将此类文件/文件夹移动到用户配置文件之外的其他位置。查找导致错误的文件/文件夹，检查它们的路径，然后将它们移动到另一个位置。下次，您应该不会遇到此备份错误 0x8100002F。

5]使用外部磁盘进行备份

如果您使用属于同一物理磁盘一部分的硬盘驱动器进行备份，那么您也可能会收到备份错误代码 0x8100002F 并且不会进行备份。因此，您应该使用外部磁盘进行备份。无论如何，在其他磁盘上进行备份总是好的。如果第一个磁盘损坏或损坏，您的另一个磁盘将具有您需要的备份。

6]使用^(Use)第三方工具进行备份

有时问题出在Windows的内置备份和还原工具上 ，因此您无法备份文件。因此，您应该尝试一些 3 ^rd方工具来备份系统文件或其他文件。您可以尝试一些适用于 Windows 的非常好的数据恢复和备份工具。^{(data recovery and backup tools for Windows)}

希望有所帮助。

Windows Backup error code 0x8100002F when backup files in Windows 11

While taking a backup of your files in Windows 11/10, if yoυ encountеr Backup error 0x8100002F, then this post might be helpful. Such a Windows backup error may occur when you try to copy system files or create a system image, or when Windows tries to backup files in contacts, or if the system can’t find the file specified. There are some simple fixes covered in this post that might resolve this error.

Windows Backup error code 0x8100002F

1. Run CHKDSK
2. Run System File Checker or DISM tool
3. Using Registry Editor
4. Move the files or folders that cause the error
5. Use an external disk for backup
6. Use a third-party tool for backup.

1] Run CHKDSK

CHKDSK is a built-in utility in Windows 10 that helps to check the hard drive for errors, bad sectors, health, system file problems, and then tries to fix such problems. This might also work to get rid of backup error 0x8100002F. So, run the CHKDSK utility for both the drives (source and destination) and complete the process. This should work.

2] Run System File Checker or DISM tool

Both System File Checker (SFC) and DISM tools are built-in features of Windows 11/10. While the first one helps to find corrupt system files and repair them, the DISM tool helps to repair Windows Image File and Windows Component Store.

You can use System File Checker or run the DISM tool using Command Prompt window. Let the scan and repair process complete and then try to start Windows backup.

3] Using Registry Editor

It is possible that there are some user profile keys that should not be present in Registry Editor. So, removing such keys might solve your Windows backup issue. Before you try this option, you should backup Registry Editor so that you can restore it later if something wrong happens. Now follow these steps:

• Open Registry Editor
• Go to ProfileList Registry key. The path is:

HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > Windows NT > CurrentVersion > ProfileList

• Select a folder present under the ProfileList key
• On the right-hand part, look for the ProfileImagePath String value
• If the value is present, that user profile folder is OK
• If the value is not present, delete the entire folder
• Repeat all the above steps for other folders present under the ProfileList folder.

4] Move the files or folders that cause such error

Sometimes, it is just a file or folder that causes such an error. For example, most of the users have experienced this error when copying the Contacts folder present under the user profile. In such a case, simply move such a file/folder to some other location outside of your user profile. Look for the files/folders that are causing the error, check their paths, and move them to another location. The next time, you should not face this backup error 0x8100002F.

5] Use an external disk for backup

If you are using a hard drive for backup that is part of the same physical disk, then also you might get backup error code 0x8100002F and backup won’t take place. Therefore, you should use an external disk to take the backup. It is anyway always good to have a backup in some other disk. If the first disk is corrupted or damaged, your other disk will have the backup that you need.

6] Use a third-party tool for backup

Sometimes the problem is with the built-in backup and restore tool of Windows because of which you are not able to backup files. So, you should try some 3^rd party tool to backup system files or other files. There exist some very good data recovery and backup tools for Windows that you can try.

Hope something will help.
