After some research I found that it can be easily fixed. The issue occurs because most probably you have created a Shared volume and the VHDX file or Virtual Drive is in the root of the volume. To fix this, create a new folder called ‘Virtual Drives’ or whatever you wish and move the Virtual Drives onto that folder.

Restart the backup process and the issue will not occur

Fix: NTBackup fails with 0x8004231f on Windows 2003 Server

Leave a comment

When attempting to make a full server backup with Shadow Copy and everything, you may notice the error 0x8004231f whenever you try to affect a backup on your server. This is 99% due to space on one of your hard drives. There is not enough space for the Volume Shadow Copy to create a shadow copy of the files in the drive.

The full error looks like this:

Volume shadow copy creation: Attempt 1.
Error returned while creating the volume shadow copy:0x8004231f.
Error returned while creating the volume shadow copy:8004231f Aborting Backup

To fix this, you may want to either delete or move unecessary folders or files from the drive in question… or look at the Volume Shadow Copies configuration.

Right-Click on the drive and select Properties
Click on the Shadow Copies Tab
Click on the drive you are having problems
Click on Setting button

At this stage you may review the Shadow Copy storage use by increasing or decreasing the limit in MB. Once you have enough disk space for the Shadow Copy on the drive in question, run the NTBackup again and it will not cause any issues.
