Hi,
We have configured Weekly Full Backup & Daily Differential backup through maintenance plan in SQL Server 2005 with SP3 and it was working fine till this Tuesday.
On Wednesday the Daily Differential backup was failed. I have checked the error message on the log file. Also, I have tried to execute the differential backup for this database from SSMS. At that also the below mentioned same error message is coming.
Msg 3035, Level 16, State 1, Line 1
Cannot perform a differential backup for database "DBName", because a current database backup does not exist. Perform a full database backup by reissuing BACKUP DATABASE, omitting the WITH DIFFERENTIAL option.
Msg 3013, Level 16, State 1, Line 1
BACKUP DATABASE is terminating abnormally.
I checked that the last Full backup was taken successfully and it is residing on the same server.
I have tried to take the differential backup for some other database on the same instance and I am able to take the differential backup successfully for other databases.
