Error
"There was a failure in preparing the backup image of one of the volumes in the backup set 0x807800c5."
Behind the given message, there is usually some additional information that supplements the failure, for example, 'the mounted backup volume is inaccessible. Please retry the operation (0x8078004F)', 'backup disk cannot be found', or 'the version does not support this version of the file format', etc.
Cause
Preparing the backup image failed with error code 0x807800c5 suggests a conflict of the identical folders named WindowsImageBackup. To put it more specifically, when you use Windows File History, the inbuilt Backup and Restore program in Windows 10, 8 and 7, to create a system image, you save the image to a WindowsImageBackup, and the folder is set to locate at a specified location, for example, volume E: that is with adequate unused space.
Some days later, you did another system backup, and try to save it to the same folder placed in the same location. Oops, system image backup failed error prompted, saying that there is a failure in preparing the backup image of one of the volumes...
Hence, in conclusion, the catastrophe is caused by obsolete backup files in the same partition.

Clone will copy one disk to another or one partition to another (unallocated space is also supported). Usually, this option is used to upgrade the current disk by creating an identical copy. Backup will generate a .PBD image file containing the selected files or system that can be restored from the .PBD image if needed.
- What is the difference between System Backup and Disk Backup?
-
System Backup will auto-select the system boot related partition(s) as the backup source to make sure the system image can be restored properly. Disk/Partition Backup will allow you to manually select a whole disk or speficy a certain partition as the backup source.

-
You can use System Backup to back up the system and boot partitions, use Disk/Partition backup to back up the data partition and add plans to run an automatic backup. If you use the computer frequently or have software that may cause boot failure of the computer, we would suggest you back up the computer every 1 to 2 days. For other situations, you can backup the computer once a week. In addition, you can schedule File Backup to back up the files which are changed frequently.
- What kind of storage service should I use to save my backup images?
-
EaseUS Todo Backup can save backup images to internal disks, external disks, network drives, or free cloud(Google Drive, Dropbox, and OneDrive) and CD/DVD. It is suggested to save the images to the internal/external/network drives to save time as those kinds of disks have a better read-write speed. It is suggested NOT to save the image on the source disk, because once the disk is damaged, all the files on the disk will become unavailable and you will be unable to restore the image.
