Hi,
We have SQL 2008 R2 Enterprise edition. We have full DB/Txn log backups scheduled and they run fine. We have also scheduled differential backups which run at times and fails most of the time with the below error:
Cannot perform a differential backup for database "XXX", because a current database backup does not exist. Perform a full database backup by reissuing BACKUP DATABASE, omitting the WITH DIFFERENTIAL option. BACKUP DATABASE is terminating abnormally.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
Though we have full DB backup taken today morning we still get this error when tried to run now. I checked few posts and found that SQL Server VSS writer should be up and running which is already running in our server. But still this does not work.
This server is configured with Team foundation server. I am not sure if that has any impact on the DB differential failures. Can anyone help to fix this issue?
Thanks
