We have scheduled backups running in sql agent as follows:
1. Full backup at 6:00AM
2. Differential backup at 7:00AM and every hour until 6:00 PM
The differential backups are failing with the following error and I need help fixing as I do not understand why this is happening.
Cannot perform a differential backup for database "DataPak", because a current database backup does not exist. Perform a full database backup by reissuing BACKUP DATABASE, omitting the WITH DIFFERENTIAL option. [SQLSTATE 42000] (Error 3035) BACKUP DATABASE is terminating abnormally. [SQLSTATE 42000] (Error 3013). The step failed.
