Way 2. Use CHKDSK to repair disk errors

CHKDSK, a native Windows utility, can inspect hard drives for errors, identify bad sectors, address system file problems, and attempt to rectify them. This approach may prove effective in resolving the backup error 0x8100002f on Windows 7/8/10/11. Here's a simple guide:

Step 1. Open File Explorer, right-click on the targeted disk, and choose Properties.

Way 3. Run SFC and DISM scan tools

The occurrence of backup error code 0x8100002f may be attributed to corruption in system files or Windows images. In such cases, employing the combination of SFC (System File Checker) and DISM (Deployment Image Service and Management Tool) can identify and repair damaged system files and corrupted Windows image files. Follow these steps:

Step 1. Type cmd in the Windows Search box, right-click Command Prompt, and select Run as administrator.

Step 2. Then, input sfc /scannow and hit Enter to begin the scanning process. Wait for the scanning to complete, then reboot your computer.


Step 3. If SFC proves ineffective, utilize the DISM tool. Execute the following commands sequentially:
