Backups to DD Boost Repository Fail After Upgrading to Veeam Backup & Replication 12.1.1
Challenge
Jobs or tasks interacting with a Dell Data Domain repository accessed using DD Boost failed after upgrading to Veeam Backup & Replication 12.1.1 with the following error:
Failed to initialize DDBoost Library (Veeam.Backup.Common.CCppCOMException) in use. Err: 5012
Cause
This issue occurs because the Veeam Installer Service was unable to replace the existing VeeamDeploymentDll.dll with the newer one during the upgrade.
When this occurs, the following error can be found within the C:\ProgramData\Veeam\Backup\Svc.VeeamInstaller.log log file:
ERR |Failed to delete [C:\Windows\Veeam\Backup\old_12.0.0.1423_VeeamDeploymentDll.dll] file. >> |boost::filesystem::remove: Access is denied: "C:\Windows\Veeam\Backup\old_12.0.0.1423_VeeamDeploymentDll.dll" >> |An exception was thrown from thread [n/a].
Consequently, the old VeeamDeploymentDll.dll is unaware of the updated DD Boost library (libDDBoost.dll) included with Veeam Backup & Replication 12.1.1, which causes initialization errors.
Solution
Restart the machine assigned as the Gateway Server for the Data Domain Repository.
Alternatively, upgrade to the latest version of Veeam Backup & Replication as this issue was resolved starting in version 12.2.
