Fixed: Windows Backup Failed While Determining Libraries Location - MiniTool

Encountering the Windows Backup error 0x81000031 ("Windows Backup failed while determining libraries location...")? This guide offers solutions and introduces a reliable alternative.

Understanding the Error

Data loss is a significant threat. While Windows Backup and Restore is a built-in solution, error 0x81000031 often arises due to inaccessible custom libraries (located on removable media or network drives). The system can't access these during the backup process.

Solutions

1. Restore Default Libraries:

This method replaces custom libraries with the standard Windows libraries (Documents, Pictures, etc.).

• Step 1: Open File Explorer and locate "Libraries" in the left navigation pane.
• Step 2: Right-click "Libraries" and select "Restore default libraries." This will remove any custom libraries and restore the defaults.

Retry the Windows Backup after this step.

2. Run System File Checker (SFC):

System file corruption can also cause this error. SFC scans and repairs corrupted system files.

• Step 1: Open Command Prompt as administrator (search for "cmd," right-click, and select "Run as administrator").
• Step 2: Type sfc /scannow and press Enter. Allow the process to complete.

Additionally, run CHKDSK to check for disk errors: Type chkdsk /f /r in the Command Prompt and press Enter.

3. Alternative: MiniTool ShadowMaker

For a more robust and reliable backup solution, consider MiniTool ShadowMaker. This third-party software provides features like scheduled backups, incremental backups (only backing up changed files), and system image creation.

• Step 1: Download and install MiniTool ShadowMaker.
• Step 2: Launch the software and select "Keep Trial."
• Step 3: Under "Backup," choose your backup source (files and folders) by clicking "SOURCE > Folders and Files."
• Step 4: Select an external drive as the destination.
• Step 5: Click "Back Up Now" to initiate the backup.

Conclusion

By implementing these solutions, you can resolve the 0x81000031 error and ensure your data is safely backed up. For a more comprehensive and reliable backup strategy, a dedicated backup application like MiniTool ShadowMaker is highly recommended.
