The first thing that may cause you to experience error 0x81000031 is when you've created custom libraries that your computer can't access during the backup process. Your Windows computer may fail to determine the location of such libraries if you save them on a network drive or removable media.
To solve this issue and back up your system normally, you'll need to restore your default libraries, i.e., Pictures, Documents, Videos, and Music. You can achieve this through the following steps:
Step 1. Navigate to the Explorer windows and select "Libraries".
Step 2. Right-click on "Libraries" and click on "show more options" to check the available options.
Step 3. Next, click on "Restore default libraries". This step will delete all the custom libraries you had created and restore the default ones.
Step 4. Start over the backup process to check if this fix has solved the error. The system will seamlessly save your files and data if all is well.
Sometimes, your computer may fail to determine the location of your default libraries because of bad sectors in your disk. You'll therefore need to fix the bad sectors for your system to backup data normally. Below are steps to check for bad sectors:
Step 1. Open Command Prompt as an administrator.
Step 2. Type and following command and press Enter: chkdsk/f/x.
Step 3. Follow the instructions displayed on your screen to finish the checkup process.
Step 4. Once the checkup process finishes, restart your device to check whether it has solved error 0x81000031. If bad disk sectors were the problem, your system should now work correctly after the restart.
Another reason Windows backup may fail to find library locations is a failed image backup system. To solve the issue, you'll need to delete the existing image backup and create a new one. You can achieve this through the following steps:
Step 1. Open Command Prompt as an administrator.
Step 2. Type the command: dir/s/aF:\WindowsImageBackup where F is the backup letter for your external hard drive. Next, press Enter.
Step 3. To delete the existing image folder, type the following command and press Enter: rd/s/qF:\WindowsImageBackup
Your system will now delete the old image backup. Repeat the backup process to create a new backup image for your files and data.
Windows may also fail to locate Libraries because of corrupted system files. To fix this issue, you'll need to run the System File Checker (SFC) command using the steps below:
Step 1. Navigate to the search bar and type cmd. Click on "Run as administrator".
Step 2. Type this command: chkdsk:/f and press Enter.
Step 3. Next, type the command: sfc /scannow (take note of the space after "sfc.”) Press "Enter".
Step 4. The system will scan and repair corrupt system files on your computer. This process can take about 20 minutes, so you should be patient until it completes. Next, restart your computer and check if this fix solved the error.
