Thank you for the reply.
When I try to run the Truncate Log job it gives me the following error message:
Msg 3023, Level 16, State 3, Procedure 'stored procedure name', Line 5
Backup and file manipulation operations (such as ALTER DATABASE ADD FILE) on a database must be serialized. Reissue the statement after the current backup or file manipulation operation is completed.
Msg 3013, Level 16, State 1, Procedure 'stored procedure name', Line 5
BACKUP LOG is terminating abnormally.
