Summary

The SQL Server Agent job named "Backup BizTalk Server" does not provide functionality for deleting backup files that have accrued over time. This can cause the disk that houses the backup files to fill up which can eventually cause the Backup BizTalk Server job to fail or other problems associated with limited disk space to occur.

More Information

To workaround this issue follow these steps:

1. Start SQL Server Management Studio.
2. Launch the Query Editor.
3. Connect to the BizTalk Management database (BizTalkMgmtDb by default)
4. Execute the following SQL Script to create the stored procedure sp_DeleteBackupHistoryAndFiles

   CREATE PROCEDURE [dbo].[sp_DeleteBackupHistoryAndFiles] @DaysToKeep smallint = null

   AS

   BEGIN

       set nocount on

         IF @DaysToKeep IS NULL OR @DaysToKeep <= 0

         RETURN

       /*

         Only delete full sets

         If a set spans a day such that some items fall into the deleted group and the other doesn't, do not delete the set

       */

    

       DECLARE DeleteBackupFiles CURSOR

       FOR SELECT 'del "' + [BackupFileLocation] + '\' + [BackupFileName] + '"' FROM [adm_BackupHistory]

       WHERE  datediff( dd, [BackupDateTime], getdate() ) >= @DaysToKeep

       AND [BackupSetId] NOT IN ( SELECT [BackupSetId] FROM [dbo].[adm_BackupHistory] [h2] WHERE [h2].[BackupSetId] = [BackupSetId] AND datediff( dd, [h2].[BackupDateTime], getdate() ) < @DaysToKeep )

   datediff( dd, [BackupDateTime], getdate() ) >= @DaysToKeep

       AND [BackupSetId] NOT IN ( SELECT [BackupSetId] FROM [dbo].[adm_BackupHistory] [h2]     DECLARE @cmd varchar(400)

       OPEN DeleteBackupFiles

       FETCH NEXT FROM DeleteBackupFiles INTO @cmd

       WHILE (@@fetch_status <> -1)

       BEGIN

    

                   IF (@@fetch_status <> -2)

                   BEGIN

                               EXEC master.dbo.xp_cmdshell @cmd, NO_OUTPUT

                               delete from [adm_BackupHistory] WHERE CURRENT OF DeleteBackupFiles

                               print @cmd

                   END

    

                   FETCH NEXT FROM DeleteBackupFiles INTO @cmd

       END

    

       CLOSE DeleteBackupFiles

       DEALLOCATE DeleteBackupFiles

   END

   GO

5. Modify the "Clear Backup History" step of the Backup BizTalk Server job to call sp_DeleteBackupHistoryAndFiles rather than calling sp_DeleteBackupHistory.

6. Enable xp_cmdshell for the SQL Server instance if it is disabled (xp_cmdshell is disabled by default). See the SQL Server online help for information about enabling xp_cmdshell.
