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.
