The Backup Exec SQL Agent was not used to create the last full, differential, or log backup of this database

Hi

Im getting the above error message when i run an incremental daly backup. The full backup runs fine. as in the subject field i get the error below

SIMSSRV EVERYTHING -Incremental -- The job failed with the following error: The Backup Exec SQL Agent was not used to create the last full, differential, or log backup of this database. You must use the SQL Agent to run a full backup before you can run a differential backup or transaction log backup.

When i look in the event viewer it gives the following info

Backup- SIMSSRV.school.local\SIMS2008
V-79-57344-867 - The last Full backup of database ccsfms was not made by this application.  Run a new Full backup, then run this job again.

V-79-57344-867 - The last Full backup of database sims was not made by this application.  Run a new Full backup, then run this job again.

V-79-57344-867 - The last Full backup of database sims-historical was not made by this application.  Run a new Full backup, then run this job again.

Im using BE12 to do the full backups.

Any suggestions good people of the community?
