Windows backup error 0x800700E1, the operation did not complete successfully

If you cannot complete the Windows backup process, here are some solutions you can try to resolve this issue:

1] Run an antivirus scan

This error can be caused by a virus attack on the hard drive which ends up preventing the backup process. So as the first solution, you need to do a virus scan.

To do this, open Windows Settings using the Win + I keyboard shortcut.

Then go to Update & Security> Windows Security.

Now go to the right pane and click on Virus and Threat Protection.

On the antivirus page, you will see a Quick scan button under Current threats.

Clicking this button will launch a virus scan to detect any suspicious malware.

It will take a little while to complete the scanning process, but you can continue to use your device during this.

Once completed, you will be notified and view the scan result.

If it doesn’t show any current threats but the problem persists, you should run a full scan of your device.

To do this, click on the link labeled Scan Options, then select Full Scan> Scan Now.

Full Scan

This process may take longer (up to an hour) to scan all available files and run programs on your hard drive.

If you are using third-party security software, use it to scan your PC.

If you want, you can also scan your PC using a separate on-demand malware scanner.

When you’re done, check if this helped you resolve the issue. Otherwise, go to the next potential solution below.
