Sometimes users end up losing their data permanently after hardware failure or different types of threat attacks like ransomware. Therefore, it is always a good job of having a backup copy of the personal data to protect important information from corruption or to avoid permanent loss. Recently some users have reported a System Image Backup Error Code 0X807800C5 on their Windows 10 PC while trying to create a system image backup.
The error message you may see with this error code is – There was a failure in preparing the backup image of one of the volumes in the backup set (0x807800C5). This error code comes with additional information that states – The mounted backup volume is inaccessible, please retry the operation (0x80070020).

5. Create System Image using PowerShell
If you’re still facing the issue, it is possible that the application is undergoing a sudden malfunction or breakdown. In such a case, you need to create the system image using PowerShell. Here is how to do:
- Open Windows PowerShell as administrator.
- Once it opens, copy and paste the following commands and hit Enter:
wbadmin start backup-backup target: E:-include: C:-quiet-allCritical

- In order to extract the created system image, open the Run dialog box, type the following text, and then press Enter:
C: \ Windows \ System32 \ Shutdown.exe / r / o
- On the following page, you can now find and extract the file.
