How to Fix Windows Backup Error 0x800700E1

Windows 10 devices automatically come with a backup feature, called Windows Backup, allows you to save a copy of your important files and documents. You have two options for backup: cloud-based or via file history.

The cloud-based backup lets you save your files in the cloud and access them on multiple devices. All you need is cloud storage and an internet connection. Creating a backup using File History, on the other hand, means saving a copy of your files to another disk, preferably an external drive.

Windows Backup has made it a lot convenient for users to backup important data in a safe place, where they can be easily restored when the originals are lost, corrupted, or deleted. The backup process is usually smooth, except for when problems like error 0x800700E1 happen.

What is Error Code 0x800700E1 on Windows?

The error code 0x800700E1 is a backup issue that occurs whenever you try to use Windows Backup to save your files or copying some data to your external drive. This error basically prevents users from creating the backup and the process does not progress every time the files are copied.

This error code usually comes with this pop-up message:

An unexpected error is keeping you from copying the file. If you continue to receive this error, you can use the error code to search for help with this problem. 

Error Code 0x800700E1: Operation did not complete successfully because the file contains a virus or potentially unwanted software. 

You have two options: to try to run the backup again or change backup settings. But regardless of what option you choose, you’ll probably run into the same error again and again, as long as you try to copy the same files.

This is because the error is probably triggered by a specific file you are trying to copy, which Windows suspects as malicious. But even if Windows says the file has a virus or a potentially unwanted software, most of the time, these are just false positives.

The “Operation did not complete successfully, Windows Backup error 0x800700E1” problem is usually a product of an overactive and overprotective Windows Defender or other security programs. This security program is preventing a file from being copied just because it seems malicious.

How to Fix Operation Did Not Complete Successfully Error 0x800700E1

If you encountered this error when trying to copy your backup files, you don’t have to worry because this can be dealt with easily by following the methods below:

Step 1: Run a Scan.

Since your security program flagged one of your files as malicious, the first step you need to do is run a scan of your system using a reputable antivirus program. This will detect whether you indeed have files that are infected by a virus or a potentially unwanted software has been installed on your computer. Your antivirus program should also help you clean up all these threats on your computer.

You can also use Windows Defender to check your PC for infections. To do this:

This should initiate the virus scan on your computer, which might take a little time depending on how many files need to be scanned. Once completed, you see the results of the scan. You can also choose Scan options > Full scan > Scan now for a deeper scan.

Step 2: Disable Your Security Software Temporarily.

If you did not find any infected files on your system, then the error is probably reacting to a false positive. If you’re confident that your computer is clean and does not have malware, you can temporarily disable your antivirus or anti-malware program while performing your backup tasks. For third-party security programs, you can disable it using the app’s dashboard.

For those who are relying on Windows Defender, you can temporarily disable the protection by doing the steps below:

  1. Click on the Start button, then type in Windows Security in the search bar.
  2. From the search results, choose Windows Security.
  3. Alternatively, you can press Windows + I to open Settings, then select Update & Security > Windows Security.
  4. In the Windows Security window, click Virus & threat protection.
