Windows Backup failure creating system image
Solution 1:
Realistically, you are wasting your time.
Windows Backup is deprecated. Microsoft has stopped its development and is recommending using third party software for backups.
We are seeing on this site an increasing number of errors with Windows Backup both in creating the backup and (much more worryingly) with restoring the data. Several posts on our site bear testimony. Microsoft has removed the option to use this alongside their file history, because of errors caused when scheduling both.
I suggest following Microsoft's recommendation and using a third-party product. My favorite is AOMEI Backupper Freeware, but there are other alternatives.
