The differential maintenance plan is failing with this error message "Cannot perform a differential backup for database "Search_Service_Application_CrawlStoreDB_e9b6abf77def428095e4156c66fb4e06", 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.
This is happing on a SQL Server 2012 Server Build 11.0.3128. I have verified we have a full backup. The maintenance plan is set to run every 6 hours but only fails during the 8:00 PM run. The current set up is this:
Full Backup on Weekly on Saturday at 9:00 PM
Differential Backup Daily every 6 hours starting at 2:00 AM ending at 11:59 PM
Transaction Log Backup once daily at 3:00 AM I don't know why it is set up this way as I did not set this.
One last note: This is a SharePoint database.
Any advice would be greatly appreciated - Thank You.
