如果当您尝试在 Windows 10 设备上创建系统映像备份时，操作失败并出现^{(create a system image backup)}错误代码 0x807800C5 和 0x80780081^{(error codes 0x807800C5 and 0x80780081)}，那么这篇文章旨在帮助您。在这篇文章中，我们提供了最合适的解决方案来快速解决这个问题。

准备备份集中其中一个卷的备份映像失败

当您遇到此问题时，您将收到以下完整错误消息；

Create a system image
The backup failed.
There was a failure in preparing the backup image of one of the volumes in the backup set. (0x807800C5)
Additional Information:
The specified backup disk cannot be found. (0x80780081)

系统映像备份^{(System Image Backup)}错误 0x807800C5、0x80780081

如果您遇到任何这些错误代码，您可以尝试我们推荐的解决方案，看看它们是否可以帮助您解决问题。

1. 释放目标驱动器上的存储空间
2. 从旧驱动器中删除EFI 分区（适用于多磁盘设置）^{(EFI Partition)}
3. 暂时禁用您的安全软件
4. 在干净启动状态^{(Clean Boot State)}下执行操作
5. 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]释放^(Free)目标驱动器上的存储空间

如果您尝试在存储空间不足的外部驱动器上创建系统映像，则很可能会遇到此错误。在这种情况下，您应该通过将文件传输到另一个驱动器或将文件移动到云存储服务^{(cloud storage service)}来释放目标驱动器上的磁盘空间。

从磁盘中移动文件或目标磁盘上没有重要数据后，您现在可以将其格式化为 NTFS^{(format it to NTFS)}，然后再次开始创建系统映像。

2]从旧驱动器中删除EFI分区（适用于多磁盘设置^(Remove)）^{(EFI Partition)}

具有以下类似配置的 PC 用户遇到此问题：

Windows最初安装在磁盘上，但后来将安装移动/迁移到同一台计算机上的另一个磁盘。格式化旧磁盘，一半用于系统映像备份^{(System Image Backup)}，一半用于存储。现在，在旧磁盘上创建系统映像备份会触发这两个错误。在这里，问题是旧驱动器仍然具有以前Windows的这两个分区（ ^(Windows)EFI System Partition和Recovery Partition ） 。

在这种情况下，要解决此问题，请打开磁盘管理^{(open Disk Management)}并删除^{(delete )}这两个分区。或者，您可以使用 DiskPart^{(use DiskPart)}删除分区。删除后，重新启动计算机并再次尝试系统映像备份 - 操作应完成且不会出现这些错误。

3]暂时^{(Temporarily)}禁用您的安全软件

您可以暂时禁用安全软件，然后运行系统还原^{(System Restore)}，看看是否对您有帮助。

4]在干净启动状态下^{(Clean Boot State)}执行^(Execute)操作

使用最少的驱动程序和启动程序集执行干净启动^{(Clean Boot is performed)}以启动Windows。这有助于消除软件冲突。在干净启动状态下，您可以查看操作是否成功完成。

5]使用第三方成像软件

如果上述解决方案均无效，您可以使用任何 适用于Windows 10的^{(Windows 10)}第 3 方映像、备份和恢复软件^{(3rd party Imaging, Backup, and Recovery Software)}来创建系统映像备份。

希望这可以帮助！

Failure in preparing Backup image, Errors 0x807800C5, 0x80780081

If when you attempt to create a system image backup on your Windows 10 device, and the operation fails with the error codes 0x807800C5 and 0x80780081, then this post is intended to help you. In this post, we provide the most suitable solutions to quickly resolve this issue.

Failure in preparing the backup image of one of the volumes in the backup set

When you encounter this issue, you’ll receive the following full error message;

Create a system image
The backup failed.
There was a failure in preparing the backup image of one of the volumes in the backup set. (0x807800C5)
Additional Information:
The specified backup disk cannot be found. (0x80780081)

System Image Backup errors 0x807800C5, 0x80780081

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. Free up storage space on the target drive
2. Remove the EFI Partition from the old drive (applies to multiple disk setup)
3. Temporarily disable your security software
4. Execute the operation in Clean Boot State
5. Use third-party imaging software

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

1] Free up storage space on the target drive

If you’re trying to create the system image on an external drive with insufficient storage space, you’re most likely to encounter this error. In which case, you should free up disk space on the target drive, by transferring your files to another drive or moving your file to a cloud storage service.

After you have moved your files from the disk or there is no important data on the target disk, you can now format it to NTFS and then start to create a system image again.

2] Remove the EFI Partition from the old drive (applies to multiple disk setup)

PC users who had the following similar configuration were experiencing this issue:

Windows was originally installed on a disk but later moved/migrated the installation to another disk on the same computer. Formatted the old disk to use half for the System Image Backup and a half for storage. Now, creating the system image backup on the old disk triggers these two errors. Here, the problem was that the old drive still had those two partitions ( EFI System Partition and Recovery Partition) from the previous Windows.

In this scenario, to fix the issue, open Disk Management and delete those two partitions. Alternatively, you can use DiskPart to delete the partitions. Once deleted, restart your computer and try the system image backup again – the operation should complete without these errors.

3] Temporarily disable your security software

You may temporarily disable your security software and then run System Restore and see if that helps you.

4] Execute the operation 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. In a clean boot state, you can see if the operation completes successfully.

5] Use third-party imaging software

If neither of the above solutions worked, you can use any of the 3rd party Imaging, Backup, and Recovery Software for Windows 10 to create the system image backup.

Hope this helps!
