Hi,

We are running SQL Server 2000 SP3, I am receiving an error message in the sql log:  BACKUP failed to complete the command backup database  to VIRTUAL_DEVICE='VNBU0-3040-3984' with blocksize = 65536, maxtransfersize = 65536, buffercount = 1.  Now, the odd thing about this is that the database it is pointing to does not exist.  It did exist previously and was deleted.  The backups are performed with a maintenance plan, selecting all databases.  I have deleted and recreated the maintenance plan and am still getting the error message.  We also use NETBACKUP, but it only backs up the .bak files.  Any ideas would be appreciated.  THANKS!

 Hi,

All maintenance plans db will be stored in the table 'sysdbmaintplan_databases' in msdb database. please check there once.

Thanks.

true said, you need to check sysdbmainplan_history table in MSDB database, againts the database name which was exists earlier and remove the records if they exists.

I have checked both the sysdbmaintplan_history and sysdbmaintplan_databases tables and the database that is giving the error is not in either table.  I am still periodically getting this same error.
