Windows backup - the interface is unknown 0x800706B5

original title: 800706B 5

After you select Backup "Files" and after selecting what who and where, I get "unknown interface Ox800706B5" error message from Windows backup even if a full backup on the same hard drive worked fine. I am backup on an external USB hard drive.

This routine worked well for 30 months. After getting above error, I formatted the hard drive external and then made all the full backup and it worked ok but not the backup tracking "files only".

Hello

The error message that you provided does not seem to be correct, please provide us with the exact error message and the error code.

You try to perform a backup in clean boot mode. You can use a clean boot to load only the Microsoft process to see if this happens because of something in the operating system or a third-party program. Please visit the below mentioned link to run the computer in clean boot mode.

Also check if the file is saved is used during the backup process. If there are any files that are used, you can close them before starting a backup copy.

Kind regards
