Consider the following scenario:
Note In these errors, "Event Time" is a placeholder for the time that the error occurs, and "Folder Location" is a placeholder for the location of backup folder.
<Error Time> Backup Error: 3201, Severity: 16, State: 7.
<Error Time> Backup Cannot open backup device '<Folder Location>'. Operating system error 0x80770006 (failed to retrieve text for this error. Reason: 15105).
This problem occurs because the SQL Server server and the SQL Server client use different versions of the Sqlvdi.dll file when you perform a VDI backup operation.
When you install SQL Server 2008 R2, the on-disk copies of Sqlvdi.dll file in SQL Server 2005 or in SQL Server 2008 are overwritten by the Sqlvdi.dll file in SQL Server 2008 R2. However, the old version of the Sqlvdi.dll file remains in the memory when the instances are running during the installation.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
To resolve this issue, restart each older version of the instance of SQL Server that may have been running during the installation of SQL Server 2008 R2 instance. To prevent this problem, before you install SQL Server 2008 R2, follow these steps:
You can use SQL Server Backup Simulator to detect which version of the Sqlvdi.dll file is installed. For more information about how to use SQL Server Backup Simulator, go to the following Microsoft website:
