0x8004230F or Error: VSSControl: -2147212529 (VSS_E_UNEXPECTED_PROVIDER_ERROR)


You receive errors on backup or replication processes during VSS guest processing.


0x8004230F translates to the VSS error “VSS_E_UNEXPECTED_PROVIDER_ERROR”, which generally means that the backup process could not initialize due to a third party VSS Provider component installed on the system. You can verify this by opening an elevated CMD prompt and typing VSSADMIN LIST PROVIDERS on the guest which is failing to backup.

User-added image

If more than the default software provider is installed, another third party software suite may have enabled its provider on the guest.  When this provider remains on the system when backup has ceased, it may cause problems for native backup and other tasks that attempt to initiate a VSS backup. This component of the third party software will need to be removed if Veeam Backup & Replication is to process this source guest consistently.

For more information on removing specific providers, please refer to vendor documentation regarding VSS Provider and Agent installation. In some instances, the VSS Provider component can be removed while keeping the rest of the software functionally intact.
