File History not working in Windows 11 for system backup. Any good alternative?

If Windows built-in backup feature is giving you trouble, there is another option worth considering. File History not working in Windows 11 may lead you to look for a way to preserve an entire Windows partition, and DISM can capture and apply a Windows image using the command line.

How to Fix File History Not Working in Windows 11

Step 1: Boot into Windows PE or another suitable Windows recovery environment, and identify the Windows partition and the external backup drive.

Step 2: Verify that drive E: is the external drive and that it has sufficient free space to accommodate the image file.

Step 3: Before proceeding with the recovery, back up all important files on the target partition, as applying the image may overwrite existing data.

Finally, enter the recovery environment and verify that both E:\backup.wim and the target partition are accessible.

The Three Most Important Commands：

1. Capture the Windows partition as a WIM file by running the following command:

dism /Capture-Image /ImageFile:E:\backup.wim /CaptureDir:C:\ /Name:“Windows11” /Compress:max /CheckIntegrity

2. Apply the saved image to the Windows partition using the following command:

dism /Apply-Image /ImageFile:E:\backup.wim /Index:1 /ApplyDir:C:\

3. If necessary, assign a drive letter to the EFI system partition and recreate the boot files using the following command:

bcdboot C:\Windows /s S: /f UEFI

One thing to remember：

Drive letters may change in the recovery environment, so be sure to verify the actual Windows partition and EFI partition before executing the restore command. Another thing you should know is that this method is more complex than using standard backup tools.
