2. 删除旧的备份文件
3. 在干净启动状态^{(Clean Boot State)}下执行系统映像备份^{(System Image Backup)}
4. 使用第三方成像软件

让我们看一下关于列出的每个解决方案所涉及的过程的描述。

1]运行SFC扫描

由于系统文件损坏或旧备份驱动器上的备份文件存在问题，可能会出现此问题。

此解决方案要求您 在安全模式下运行 SFC 扫描，然后尝试备份系统映像，看看问题是否会得到解决。如果未解决，请尝试下一个解决方案。

2]删除旧的备份文件

考虑外部驱动器中的旧备份文件已过时并将它们删除，或将它们移到临时文件夹中。

• 数据文件——MediaID.bin^{(Datafile – MediaID.bin)}
• 文件夹 – Windowsimagebackup^{(Folder – Windowsimagebackup)}
• 计算机名^{(Computer-name)} （文件名）

运行系统映像备份操作，如果问题仍然存在，请尝试下一个解决方案。

3]在干净启动状态^{(Clean Boot State)}下执行系统映像备份^{(Perform System Image Backup)}

使用最少的驱动程序和启动程序集执行干净启动^{(Clean Boot)(Clean Boot)}以启动Windows。这有助于消除在Windows 10^{(Windows 10)}中运行程序时发生的软件冲突，因为错误提示中的其他信息可能会表明这一点。一旦您的设备处于干净启动^{(Clean Boot)}状态，请尝试映像备份操作，看看问题是否已解决。否则，请尝试下一个解决方案。

4]使用第三方成像软件

如果此时您无法解决手头的问题，您可以使用任何 适用于Windows 10的^{(Windows 10)}第 3 方映像软件^{(3rd party Imaging software)}来创建系统映像备份。

If you’re faced with any of these error codes, you can try our recommended solutions and see if any of them help you resolve the issue.

1. Run SFC scan
2. Delete old backup files
3. Perform System Image Backup in Clean Boot State
4. Use third-party imaging software

Let’s take a look at the description of the process involved concerning each of the listed solutions.

1] Run SFC scan

This issue could occur due to corrupt system files or due to issues with the backup files on the old backup drive.

This solution requires you to run SFC scan in Safe Mode, then try the system image backup afterward and see if the issue will be resolved. If unresolved, try the next solution.

2] Delete old backup files

Consider the old backup files in the external drive obsolete and delete them, or move them away into a temporary folder.

• Datafile – MediaID.bin
• Folder – Windowsimagebackup
• Computer-name (file name)

Run the system image backup operation and if the issue persists, try the next solution.

3] Perform System Image Backup in Clean Boot State

A Clean Boot is performed to start Windows by using a minimal set of drivers and startup programs. This helps eliminate software conflicts that occur when you run a program in Windows 10 as the additional information on the error prompt might indicate. Once you get your device in Clean Boot state, try the image backup operation and see if the issue is sorted. Otherwise, try the next solution.

4] Use third-party imaging software

If at this point nothing has worked for you to resolve the issue at hand, you can use any of the 3rd party Imaging software for Windows 10 to create the system image backup.

Hope this helps!
