BUG/COMPATIBILITY: Installing SQL Server 2012 beside SQL Server 2008 causes T-LOG backups to hang at end RRS feed

  • Question

  • During our testing of SQL Server 2012 RC0, we have noticed that when the product is installed beside SQL Server 2008, tlog backups will hang at the very end intermitently.  The application performing the backup is using the SQL Server VDI API.  There appears to be a compatibility issue between SQL 2012's VDI.DLL and the SQL 2008 data engine.  When the application sends a VDI ABORT request the virtual device set, VDI then "unfreezes" and the backup completes successfully (doesn't abort)!

    I'd like to enter a formal bug report for this issue, but cannot find a place to do this.

    Please advise.

    Please include sufficient information about the application that is using the VDI information. It is a 3rd party product, please include the name in the bug report.
