How to Fix Windows Backup Error Code 0x81000033?

Try the following solutions that might help you a lot after triggering this error code.

Solution 1: Spare Some Disk Space by Using Disk Cleanup

You can first go and check if there is enough free space on the root drive. Once this error code appears, you are supposed to take advantage of Disk Cleanup to release more free space. Then restart your PC, create a system back up again. If the backup error code 0x81000033 still arises, you may try the following solution.

Tip: In addition to this method, you can also free disk space in other ways. There is a relevant article about that – 10 Ways to Free up Disk Space in Windows 10/11.

Solution 2: Increase the Size of System Reserved Partition

Not having enough free space inside the Windows 10 partitions is the prior reason for 0x81000033, so expanding the space of System Reserved Partition is a very useful method when your computer suffers from the heavy pressure of partition space.

To fix backup error code 0x81000033 in this way, you can create a system volume and then appoint it as the new system reserved partition.

Step 1. Type Win + E to choose File Explorer and check all the existed driver letters. Launch the Command Prompt as an administrator. 

Step 2. Copy “bcdboot.exe /s C:\Windows /s G:” in the pop-up window and click Enter. (In this code, “C” is the root drive and “G” represents the newly created system volume.) 

Step 3. Execute the following commands one after another and remember to hit Enter after each command.


DISKPART> select volume G

DISKPART> active

Step 4. Restart your PC.

Solution 3: Delete Unnecessary Language Packs 

Too many language packs not only occupy substantial disk space but also stop the system from generating restore points. As a result, you’d better remove all the unwanted language packs in the Setting of your PC.

Step 1. Click the Start menu to choose Setting.

Step 2. Select Time & Language.

Click Time & Language

Step 3. In the Language window, choose the language pack that you want to remove by left-clicking it and then click Remove.

Remove unnecessary language packs

Solution 4: Turn on the System Protection

By default, this feature remains disabled, so it is normal for you to create any restore image unsuccessfully. This solution is pretty easy if you never turn on the system protection. Just go to Setting of your PC, and click System. In the System>About window, select System protection.

Click system protection

And then choose the system drive followed by Configure in System Properties.

Click configure

In the pop-up window, check Turn on system protection.

Solution 5: Update the Outdated Device Drivers

The outdated device drivers are another important reason for triggering backup error code 0x81000033. You can follow the next steps to update drivers. Take the graphics card driver update as an example.

Step 1. Type Device Manager in the search bar and next choose the most matched one.

Step 2. Click Display adapter in the Device Manager window, right-click your graphics driver and choose Update driver.

Click update driver

Step 3. In the pop-up window, click “Search automatically for drivers”. After that, Windows will look for the latest driver software for your PC on the Internet. If there is a newer one, Windows Device Manager will download and install the newer one for you.
