Backup on Windows 10 Pro failing with 0x81000033 error

I am trying to run a backup on Windows 10 Pro but it is failing with the error

"Windows backup skipped backing up system image because one of the critical volumes is not having enough fee space. Free up some space by deleting unnecessary fails and try again." error code 0x81000033

Couple of points. Did someone with English as a second language write this? Perhaps "Windows backup cannot complete because one of the critical volumes does not have enough free space." might help? Did a programmer write it?

Perhaps this might be even better "The backup failed because volume <x> only has <y> free space and requires <z> to complete the backup" with appropriate values filled in might be more appropriate for a consumer facing so called user friendly operating system?

Or for the "This was designed by someone from Apple award" - The computer will now adjust your setting to allow the backup to complete successfully without you having to Google for the hack.

I look forward to this solution one day.

Anyway, my set up is

Disk 0: E: 1TB. 10% free, one partition

Disk 1: 1TB. Three partitions: System Reserved partition: 100MB; C: 930GB, 10% free and 445MB Recovery partition

I'm backing up to an external drive which has 1463Gb free.

How do I fix this without doing a backup first, which of course I can't do due to the lack of working backup software.

thanks

"Every time I try to use the Backup and Restore (Windows 7) tool I get the above error code"





If you have Windows 10 Pro, the Backup and Restore feature is only to recover a previous backup that you made if you upgraded to 10 from 7. You have to turn on File History to enable file backup in Windows 10 but that does not back up your system files. You need a system image solution like Macrium Reflect or Acronis True Image for that. Or you can follow this tutorial -
